In this Class 9 Artificial Intelligence topic from Communication Skills-I, students learn how communication moves from a sender to a receiver through a message and a suitable channel, and how feedback completes the cycle. They explore the roles of encoding and decoding, recognise the importance of context, and see how noise or other barriers can affect meaning. The topic helps them understand clear, effective communication in everyday and AI-related interactions.
Practice questions
01 A notice-board message has a clear title, but it does not state whom the notice is intended for. Which weakness does this show?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Target audience not specified
Explanation: A notice should identify its intended readers so that people can decide whether the information applies to them. In this case, the title is already clear, but the audience is missing. Therefore, the weakness is an unspecified target audience, not an unclear title, excessive wording, or excessive use of pictures.
02 Which option presents the most organized order for a message?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Purpose, necessary details, then expected action
Explanation: An organized message normally begins by telling the receiver why the message is being sent. It then supplies the details needed for understanding and ends by stating the action expected from the receiver. Option A follows this logical sequence, while the other orders delay or obscure the main purpose.
03 If a report is well written but does not include a conclusion, what effect may it have on the reader?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. The report’s final message or main finding may remain unclear.
Explanation: A conclusion brings together the important findings and tells the reader what overall message follows from the report. Even clear paragraphs may leave the final meaning uncertain when this closing part is missing. A conclusion does not add sources automatically, but it gives the report a clear ending and helps readers remember its main result.
Correct answer: A. Please submit your photograph by tomorrow for the school identity card.
Explanation: Option A identifies the required item, the deadline, and the reason for submitting it. The receiver therefore knows what to do, by when, and for what purpose. The other messages use vague words such as “item,” “soon,” or “that work,” so they leave important details and the exact purpose unclear.
05 If a sender does not seek feedback after sending a message, what risk remains?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. It will remain unknown whether the receiver has understood the message correctly.
Explanation: Feedback checks whether the receiver has understood the intended meaning and knows what action is required. Without it, confusion, missing information, or an incorrect interpretation may remain hidden. Sending a message alone does not make it clearer, guarantee correct action, or cause the communication channel to repair errors automatically.
06 Which message demonstrates both completeness and correctness?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Please attend the meeting in Room 5 at 9 a.m. on Friday.
Explanation: Option A is both complete and correct because it gives the required action—attending the meeting—as well as the specific day, time, and place. These details allow the receiver to understand the message and act without seeking further information. Its wording is clear and grammatically appropriate. Option B lacks a definite time, option C lacks a definite location, and option D does not confirm that the meeting will take place.
07 What should be identified first in medium-level communication questions?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. The main communication problem in the situation
Explanation: Situation-based communication questions usually contain a problem involving a barrier, channel, listening behaviour, feedback, or communication style. Identifying that central problem first helps the learner compare each option with the actual situation. Choosing by length, position, or colour is unrelated to meaning and cannot reliably produce a correct answer.
08 Why is it useful to state the main idea at the beginning of a message?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. It helps the listener understand the purpose and direction of the message.
Explanation: Stating the main idea early gives the receiver a clear frame for interpreting the details that follow. The listener knows the subject and purpose, can identify important information, and can respond more appropriately. It does not prevent feedback or remove the sender’s responsibility; instead, clarity usually makes useful feedback easier.
Correct answer: B. Meet in the library tomorrow at 9 a.m.
Explanation: A concrete message contains specific details that leave little room for guessing. Option B tells the receiver the action, place, day, and exact time. “Soon,” “sometime,” and “the work” are vague expressions because they do not identify a precise time, place, or task. Specific information makes planning and correct action easier.
10 Which quality of communication improves when unnecessary details are removed from a message?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: B. Conciseness
Explanation: Conciseness means expressing the required meaning with no unnecessary words or details. Removing irrelevant material makes a message shorter and easier to follow while preserving its essential content. Completeness is different: it requires including all information needed by the receiver. Noise and emotional barriers are problems, not qualities improved by editing out extra details.
11 Mentioning the date, time, place, and task to be done in a school notice strengthens which quality?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Completeness
Explanation: A complete notice contains all details that readers need in order to understand and act on it. Date, time, place, and task answer the basic questions of when, where, and what to do. Leaving out any of these may force readers to guess or seek clarification. Silence, informality, and physical distance do not describe this quality.
12 In the communication process, what is the response given by the receiver after understanding a message called?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Feedback
Explanation: Feedback is the receiver’s response to a message, such as an answer, question, confirmation, or action. It tells the sender whether the intended meaning was understood and whether further explanation is needed. The sender transmits the message, the channel carries it, and encoding changes an idea into symbols; none of those is the receiver’s response.
13 What is the main purpose of the conclusion in a good presentation?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. To briefly summarize the main points
Explanation: The conclusion gives the audience a final, organised reminder of the presentation’s central ideas and often reinforces the main message or action. It should not introduce a completely new topic, end without closure, or block questions automatically. A clear summary helps listeners remember what was most important after the details have been presented.
14 If the receiver reads a message but gives no reply or signal, which part of the communication cycle remains incomplete?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. प्रतिक्रिया | Feedback
Explanation: Feedback is the receiver’s response, acknowledgement, or signal that shows whether a message has been received and understood. In this situation, the sender has sent the message, the message exists, and the channel has carried it to the receiver. Because no reply or signal is provided, the feedback stage is incomplete. Thus, option A is correct.
15 Which of the following is an example of poor feedback?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. तुम्हारा काम बेकार है। | Your work is useless.
Explanation: Poor feedback is vague, insulting, and unusable. “Your work is useless” attacks the work without identifying a problem or explaining how to improve it. The other options mention specific strengths or weaknesses and give an actionable suggestion, which makes them more constructive and useful.
16 In the communication process, what does the receiver’s feedback help the sender understand?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. संदेश को कितनी सही तरह समझा गया | How accurately the message was understood
Explanation: Feedback gives the sender information about the receiver’s response, including whether the intended meaning was understood, whether clarification is needed, or whether further action should be taken. Option A states this purpose directly. The chosen channel, sending time, and speaking speed may be relevant details, but feedback does not primarily determine them. Therefore, A is correct.
17 In which situation will feedback be called constructive?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. गलती बताकर सुधार का तरीका भी बताना | Pointing out the error and suggesting improvement
Explanation: Constructive feedback is specific, respectful, and aimed at improvement. It identifies what needs attention and gives a practical way to do better, as in option A. Mockery and unsupported criticism hurt without guiding the person, while silence provides no information or opportunity for correction.
18 Which option most clearly describes the purpose of communication?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. विचारों, सूचनाओं या भावनाओं को इस प्रकार साझा करना कि उनका अर्थ समझा जा सके | Sharing ideas, information, or feelings so their meaning is understood
Explanation: Communication is more than producing sounds or sending unrelated words; it is the purposeful sharing of ideas, information, or feelings so that another person can understand the intended meaning. Option A includes this shared understanding. The other options remove purpose, meaning, context, or feedback, which weakens communication.
19 If a person says, “I will repeat your point so that there is no confusion,” which purpose of communication is being served?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Confirming the message and ensuring shared understanding
Explanation: Repeating another person’s point in one’s own words is a useful form of active listening and feedback. It gives the original speaker an opportunity to confirm or correct the interpretation. This process builds shared understanding and reduces misunderstanding. It is not meant to change the topic, delay the response, or reveal confidential information.
20 If a notice is intended for students of all classes but is sent only to one class group, what is the most likely communication problem?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. The reach of the information will remain limited
Explanation: The intended audience includes students from every class, but the selected channel reaches only one class group. Students outside that group may never receive the notice, so its reach is limited. Delay, excessive feedback, and information overload are not the direct problems described. The sender should use a channel that covers all intended recipients.
21 If everyone is speaking in a discussion but nobody is listening, what rule should be made first?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Rule of turn-taking and summarizing
Explanation: When people speak at the same time, voices overlap and important points are lost. A turn-taking rule gives each person a fair opportunity to speak and listen. Asking the next speaker to summarize or restate the main point checks understanding and reduces confusion. Allowing simultaneous speech, stopping questions, or changing the topic does not solve the listening problem.
22 If a person does not listen fully while speaking with someone but later claims to have understood, what risk exists?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Understanding may be incomplete or wrong
Explanation: Understanding depends on listening to the complete message, including conditions, examples, and the speaker’s intended meaning. If a person listens only partly, they may fill gaps with assumptions and act on an incorrect interpretation. Claiming to understand is not proof of understanding. Summarising the message and asking a clarifying question provide better confirmation.
23 If a message is clear to the sender but is not understood by the receiver, on what basis will the success of communication be judged?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: B. By the receiver's understanding
Explanation: Communication is effective when the receiver understands the intended meaning, not merely when the sender believes the message is clear. The receiver's understanding and feedback provide evidence of success. Presentation style and length can influence clarity, but neither proves that the meaning was understood. Thus, option B is correct.
24 If a notice has been changed but the reason for the change is not given, which question is most appropriate for clarification?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Why has this change been made?
Explanation: The missing information is the reason for the change, so a clarification question should directly ask about that cause. Option A does exactly this and can lead to a transparent explanation. The paper colour, picture, and display time may describe the notice, but they do not explain the decision behind the change. Therefore, A is the only relevant question.
25 If a notice has been changed and a new notice has been issued, but the reason for the change is not stated, which question is most appropriate?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: B. What is the reason for the change?
Explanation: The missing information concerns the purpose or reason behind the revision, so asking why the change was made is directly relevant. Knowing the reason helps readers understand which instruction is current and why they should follow it. Paper thickness, picture authorship, and colour do not explain the substantive change in the notice.
