Communication cycle and its elements

Correct answer: A. Obtaining acknowledgement of receipt

Explanation: Acknowledgement confirms that the intended person has received and noticed the message. This is especially important for urgent or time-bound work. The channel was already selected and the message was drafted and sent, while progress feedback would come later. The missing immediate step is therefore confirmation of receipt.

Correct answer: A. How were these results obtained?

Explanation: The method explains how data were collected, processed, or tested, so it is essential for judging whether the results are trustworthy and meaningful. Asking how the results were obtained directly addresses this missing information. Questions about colours, duration, or refreshments do not examine the basis of the findings.

Correct answer: A. Speak in turns and give a summary at the end

Explanation: Taking turns reduces interruptions and gives each participant a fair opportunity to speak and listen. A final summary collects the main points, identifies agreement or disagreement, and supports a conclusion. Allowing simultaneous speech increases noise, suppressing questions reduces understanding, and changing the topic avoids rather than solves the discussion problem.

Correct answer: A. The message is polite, but the recipient selection is incorrect.

Explanation: Politeness is one quality of communication, but effectiveness also requires reaching the intended person. Sending a message to the wrong recipient may cause misunderstanding, prevent the right action, or expose private information. A good intention cannot remove this risk, so recipient checking remains necessary even when the wording is courteous.

Correct answer: A. Whether the message is clear to the receiver

Explanation: Clarity is judged by whether the receiver understands the intended meaning, not by the sender’s confidence. The speaker should seek feedback and check wording, sequence, examples, assumptions, and the communication channel. A louder voice, thicker paper, or more colours may improve presentation in limited situations, but none automatically corrects unclear meaning.

Correct answer: A. People will be confused between the old and new details.

Explanation: A correction should identify the original error and state the replacement information precisely. If the changed part is not named, recipients may continue using the old detail, overlook the new one, or combine both versions incorrectly. A vague correction therefore creates further ambiguity; it does not automatically shorten the message or improve confidentiality.

Correct answer: A. Deep confirmation of meaning

Explanation: Asking the listener to explain the message in their own words checks whether the intended meaning was received correctly. It is stronger than asking only, “Did you understand?”, because a person may say yes without actually understanding. The listener’s explanation can reveal confusion early. Therefore, option A is the correct form of meaning confirmation.

Correct answer: A. How was agreement confirmed?

Explanation: “Everyone agrees” is a broad claim that requires evidence, especially when the decision matters. Without a written response, meeting record, or clear confirmation from participants, it is impossible to know whether people agreed, stayed silent, or were not consulted. Therefore, the important question is how agreement was confirmed. The other options do not test the claim.

Correct answer: A. Members may remember different conclusions

Explanation: A discussion can be productive yet leave different participants with different understandings of the decision, deadline, or responsibility. A final summary creates shared meaning by restating the agreed points, assigned tasks, and next steps. Without it, later disagreement and missed work become more likely. Therefore, option A is correct; the other options ignore the value of closure.

Correct answer: A. Understanding may be incomplete

Explanation: A claim of understanding is not enough evidence of learning. Asking the student to paraphrase or give an example checks whether the idea has actually been understood and connected to meaning. Inability to explain may show confusion, weak recall, or incomplete understanding, so the teacher should clarify and check again. Hence, option A is correct.

Correct answer: A. Speak while also listening carefully to others

Explanation: The governing concept is two-way communication supported by active listening. In a group discussion, a participant should express ideas clearly, allow others to speak, listen carefully, and respond appropriately. Therefore, option A is correct. Speaking continuously, interrupting, or refusing to give feedback prevents equal participation and weakens understanding among group members.

Correct answer: C. Medium or delivery

Explanation: The governing concept is the communication cycle, which includes the sender, message, channel or medium, receiver, and feedback. If the message fails to reach the intended person, the problem is normally in the channel, addressing, or delivery process. Hence option C is correct. Sender emotion, message colour, and facial expression may affect interpretation, but they do not explain a delivery failure in this situation.

Correct answer: D. Adjust pace or explanation as needed

Explanation: The governing concept is feedback in the communication cycle. Audience expressions, questions, attention, and confusion provide information about whether the message is being understood. A responsive speaker uses this feedback to slow down, clarify a point, give an example, or change the pace. Therefore, option D is correct. Stopping immediately, writing a report, or staring only at slides ignores the receiver’s response and does not improve the live interaction.

Correct answer: C. Recorded advertisement

Explanation: The governing concept is the difference between two-way and one-way communication. Face-to-face discussion, telephone conversation and video meetings allow participants to respond during the interaction. A recorded advertisement is prepared in advance and normally reaches an audience without a direct response channel, so immediate feedback is least likely there. Therefore, option C is correct; the other three are interactive forms.

Correct answer: A. Repeat key points and confirm them

Explanation: The governing concept is feedback and confirmation in the communication cycle. After hearing an oral message, the receiver should repeat important points or ask for confirmation; this checks whether the intended meaning was received correctly, making A correct. Agreeing without listening, looking away, or interrupting increases the chance of missing information and does not verify understanding.

Correct answer: A. Listening to the message and asking questions

Explanation: The governing concept is the communication cycle, in which the receiver obtains, interprets, and responds to a message. Listening carefully, asking questions, and giving feedback show that the receiver is actively checking meaning rather than merely receiving sounds or words. The sender writing alone, leaving after transmission, or displaying a poster describes message creation or delivery, not the receiver’s role. Hence, option A is correct.

Correct answer: C. A recorded message on the radio

Explanation: The governing concept is feedback in the communication cycle. Communication is mainly one-way when a sender transmits information without an immediate opportunity for the receiver to respond. A recorded radio message generally follows this pattern, so option C is correct. A conversation, classroom question-and-answer session, and video meeting normally allow participants to respond, making them two-way examples.

Correct answer: D. In interpretation

Explanation: The communication cycle separates receiving a message from interpreting or decoding it. The student heard the words accurately, so the receiving of sound was successful; the error occurred while assigning meaning to those words. Therefore, option D is correct. Options A and B concern message transmission and channel choice, while option C would mean the sound itself was not received properly.

Correct answer: B. Communication also includes reception, understanding, and feedback

Explanation: The governing concept is the communication cycle: a sender creates a message, a medium carries it, a receiver interprets it, and feedback shows whether understanding occurred. Sending alone proves delivery, not successful communication. Option B is correct because reception, interpretation, and response complete the process. Option A ignores people, C wrongly removes the sender, and D incorrectly limits communication to written forms.

Correct answer: A. The teacher gives instructions and the student demonstrates the correct process

Explanation: The governing concept is feedback in the communication cycle: the receiver’s response shows whether the message was understood. In option A, the student performs the correct process after hearing the teacher’s instructions, providing observable evidence of comprehension. Merely displaying a poster, sending an email, or ending a speech proves delivery but not understanding. Therefore A is the clearest evidence that communication achieved its purpose.

Correct answer: B. Checking understanding and reducing misunderstanding

Explanation: The governing concept is feedback, especially paraphrasing or checking understanding. When the listener restates an instruction in different words, the sender can compare the intended meaning with the received meaning and correct errors early. Therefore option B is correct. The technique is not meant merely to lengthen a message, interrupt the sender, or eliminate written communication.

Correct answer: B. The medium is not delivering the message adequately to the audience

Explanation: The governing concept is that successful communication depends on both an understandable message and an effective channel or medium. Although the words are clear, very low microphone volume prevents listeners from receiving the sound adequately; hence option B is correct. Correct language and attentive listeners cannot overcome a channel that fails to transmit the message audibly.

Correct answer: A. A teacher changes the example after noticing students' confusion

Explanation: The governing concept is feedback in a dynamic communication cycle. Feedback tells the sender whether the receiver has understood the message, allowing the sender to adapt wording, examples, pace, or medium. In option A, students’ confusion prompts the teacher to change the example, so it is correct. The other situations provide no active receiver response that could guide modification.

Correct answer: B. The teacher may wrongly assume the message was understood

Explanation: The governing concept is the need for accurate feedback in the communication cycle. A nod is a non-verbal signal that may be interpreted as agreement or understanding, even when the student is confused. The teacher may therefore stop explaining and incorrectly believe learning has occurred. Option B is correct. A nod does not create a written record, guarantee effective communication, or remove a language barrier.

Correct answer: D. The message may not be received

Explanation: A communication medium works only when the receiver can access and use it. If a person cannot open, hear, read or otherwise reach the selected channel, the message may fail before understanding or feedback can occur. Option D is correct because inaccessible media prevent delivery or reception. The other options do not follow: lack of access does not make a message formal, clearer or automatically positive.
