Methods of communication

Correct answer: D. Communication requires completeness and clarity along with speed

Explanation: The governing concept is effective communication, which balances speed with clarity, completeness, correctness, and suitability for the receiver. A message that arrives quickly but omits essential details may cause confusion, delay, or incorrect action. Therefore D is correct. Speed alone cannot guarantee success; oral communication is not always wrong, and a written message need not be unnecessarily long if it contains all relevant information clearly.

Correct answer: B. Message understanding, reach, timing, feedback and achievement of purpose

Explanation: The governing concept is communication effectiveness: a method succeeds when the intended receiver gets the message on time, understands it, responds appropriately, and the communication purpose is achieved. Therefore, option B is correct because it combines comprehension, reach, timing, feedback, and outcome. Cost, message length, or the sender’s preference alone cannot prove that communication was successful.

Correct answer: B. Send a printed notice along with a mobile message

Explanation: The governing concept is choosing a communication method according to audience access and available resources. A printed notice does not depend on internet connectivity, while a mobile message can provide quick additional notification where a phone network is available. Thus option B offers two complementary channels. A website, video conference, or social-media post alone depends more heavily on internet access.

Correct answer: B. Send a written summary of the decisions

Explanation: The governing concept is selecting a clear, reliable method for formal information. A written summary records the decisions, reduces memory errors, gives every member the same wording, and can be checked later. Therefore option B is correct. Informal speech may be forgotten or misunderstood, gestures cannot communicate detailed decisions clearly, and sending no message gives members no shared record.

Correct answer: C. A written digital message with acknowledgement

Explanation: The best communication method must satisfy both requirements: a reliable record and prompt feedback. A written digital message can be stored, searched and referred to later, while an acknowledgement confirms that the recipient received it and can respond immediately. Thus option C is correct. A poster or radio announcement may reach people but gives weak individual confirmation, and a verbal announcement usually leaves no dependable record.

Correct answer: B. When the same official document must be sent to many distant people

Explanation: Email is more suitable when identical official information must reach many people who are far away and a written record is useful. It allows the sender to attach the same document, distribute it efficiently and preserve the message for later reference. Therefore option B is correct. Face-to-face discussion is stronger for emotional support, observing body language and resolving misunderstandings immediately.

Correct answer: B. Lack of immediate two-way feedback

Explanation: A recorded instructional video can provide sound, visuals and a reusable record, but it normally does not allow the viewer to ask a question and receive an immediate answer. The central limitation is therefore the lack of immediate two-way feedback, making option B correct. It is not necessarily lacking visual material or sound, and the recording itself can serve as a lasting reference.

Correct answer: B. Repeating the key steps of emergency instructions

Explanation: Repetition is useful when it strengthens understanding, memory and correct action. In an emergency, repeating the key steps can help people remember what to do under pressure and reduces the chance of missing an important instruction. Therefore option B is correct. Repeating a greeting excessively adds noise, repeating unclear words does not improve meaning, and public repetition of confidential information is unsafe.

Correct answer: A. The medium and language did not clearly indicate formality

Explanation: The tone, wording and format of a message help the receiver judge whether it is formal, official or casual. If an official order is written or delivered in an overly friendly style without clear authority, the receiver may misunderstand its status. Option A is correct. Speed of delivery, availability of feedback and literacy do not by themselves change an official message into an informal one.

Correct answer: B. The meaning of the signal will be ambiguous

Explanation: A communication signal should have a distinct and consistent meaning so that people can respond correctly. If the same bell sound represents both ordinary recess and an emergency, listeners cannot identify the intended situation; this creates ambiguity and may delay an urgent response. Therefore option B is correct. The sound does not become clearer, create written communication or change into a visual medium merely because it is reused.

Correct answer: A. Correct receiver selection and confidentiality

Explanation: The governing concept is selecting the correct receiver and protecting information privacy. A message meant for one person should be addressed only to that person, especially if it contains personal or confidential content. Sending it to a whole group creates unnecessary exposure and may cause misunderstanding. Option A identifies both the addressing error and its privacy consequence; the other options concern appearance, sound, or body language, not digital recipient selection.

Correct answer: C. A demonstration video and written steps for a complex process

Explanation: The governing concept is matching the communication medium to the message, audience, urgency, and complexity. A complex procedure is easier to learn when people can watch the actions in a demonstration and consult written steps later. Option C combines visual explanation with a durable reference. A and B provide too little detail, while D is too slow and lengthy for an emergency warning.

Correct answer: B. When incorrect or sensitive information becomes permanently recorded

Explanation: The governing concept is that written communication creates a durable record. Permanence is useful for rules, timetables, and proof, but it becomes a disadvantage when incorrect, private, or sensitive information is recorded and can later be copied, misunderstood, or shared without permission. Option B identifies that risk. Options A, C, and D describe beneficial uses of a lasting written record rather than disadvantages.

Correct answer: B. Reach increases through different media for different people

Explanation: The governing concept is using multiple communication methods to improve reach. Radio may help listeners, posters may reach passers-by, and mobile messages can reach phone users. Therefore, option B is correct because different groups can access the same information through suitable media. The other options are incorrect: using several media does not change the intended meaning, make every medium private, or automatically eliminate feedback.

Correct answer: C. Give everyone a turn to speak and respond

Explanation: The governing concept is inclusive and balanced group communication. A discussion is more effective when every participant has a reasonable opportunity to express ideas, listen, ask questions, and respond. Thus, option C is correct. Ending the discussion avoids the problem, writing-only participation excludes oral exchange, and rewarding the loudest speaker encourages domination rather than meaningful communication.

Correct answer: A. Agreement was not reliable proof of understanding

Explanation: The governing concept is confirmation of understanding in oral communication. Saying yes may show politeness or acknowledgement, but it does not prove that the instruction was understood accurately. Option A is correct because the incorrect performance reveals a gap between apparent agreement and actual comprehension. The sender should ask the receiver to restate the steps or demonstrate them. The other options make unsupported absolute claims.

Correct answer: B. Rewrite it in simple language with headings and clear points

Explanation: The governing concept is audience-centred communication: a message should be clear and suitable for the people who will use it. Option B is correct because simple words, headings, and short organised points reduce language and reading difficulty. Smaller letters would reduce readability, colour alone cannot explain complex ideas, and avoiding oral announcements may reduce access rather than improve effectiveness.

Correct answer: A. When explanations must be adjusted immediately according to questions

Explanation: The governing concept is the flexibility and immediate feedback possible in oral communication. A speaker can notice questions or confusion and change the explanation, give an example, or clarify a term at once. Therefore, option A is correct. Long-term records and legal proof usually favour written communication, while reading without a speaker is not a special advantage of oral communication.

Correct answer: A. The image may misdirect interpretation of the message

Explanation: The governing concept is that visual and written communication work together to shape meaning. Even when the headline is factual, a misleading image can create an incorrect impression or direct attention toward an unintended interpretation. Thus, option A is correct. The image can influence understanding; it does not become irrelevant, turn the news into audio, or automatically alter the headline.

Correct answer: A. Students may lack context and immediate clarification

Explanation: The governing concept is the complementary use of communication methods. Writing on the board provides a visual or written record, but oral explanation can supply context, examples, emphasis, and immediate answers to questions. Therefore, option A is correct. A record does exist, visual communication continues, and the words remain visible; the limitation is incomplete understanding without explanation.

Correct answer: A. Misinterpretation of a digital non-verbal cue

Explanation: The governing concept is non-verbal communication and the role of context in interpreting symbols. An emoji does not use spoken words; it is a digital visual or non-verbal cue whose meaning may vary with the surrounding text and the reader’s expectations. Therefore, option A is correct. The situation is not necessarily a technical failure, tactile problem, or printing error; the difficulty is interpreting an ambiguous symbol.

Correct answer: C. Broadcasting a scheduled arrival announcement at a railway station

Explanation: The governing concept is that one-way communication sends information from a source to an audience without requiring an immediate reply. A scheduled railway arrival announcement is standard, brief, and intended for many listeners, so option C is most suitable. Dispute resolution, advice, and counselling require questions, clarification, empathy, or feedback, making two-way communication more appropriate.

Correct answer: B. An evacuation order in a disaster area

Explanation: The governing principle is that communication choices should reflect risk and consequences. An evacuation order in a disaster area must reach people accurately, promptly, and reliably because a missed message can threaten safety; therefore option B is correct even if the dependable medium costs more. Casual greetings, entertainment posts, and jokes have low consequences if delayed or missed.

Correct answer: B. Inconsistency among messages

Explanation: The governing concept is consistency in multi-channel communication: the same important fact must remain identical wherever it is shared. Here, different dates create conflicting versions, so receivers cannot know which date is correct. Therefore, inconsistency among messages is the main problem. Using several media is not itself wrong, and many receivers or written records do not cause the error; the contradiction in the content does.

Correct answer: B. Giving an immediate evacuation instruction during an emergency

Explanation: The governing concept is selecting message length according to purpose, urgency, and the action required. During an emergency, people need a short, direct instruction that can be understood and followed immediately, such as “Leave through the nearest safe exit.” A scientific lesson, legal contract, or complete project report needs detail and context, so those situations are better served by longer communication.
