Methods of communication

Correct answer: D. Completeness and actionability

Explanation: The governing concept is effective message design. An instruction is actionable only when the receiver knows what must be done, who is responsible, and when it must be completed. Although the wording may be clear, omitting the deadline and responsible person leaves the task incomplete and difficult to implement. Therefore, option D is correct; visual appeal, confidentiality, and audio intensity do not supply the missing operational details.

Correct answer: A. To select a suitable and accessible medium for the receiver

Explanation: The governing concept is audience-centred communication. Before choosing a method, the communicator should consider the receiver’s language, available devices, abilities, and special needs. This analysis helps select a medium that the intended audience can understand and actually use, so option A is correct. Making a message longer, removing feedback, or serving only the sender ignores accessibility and may exclude the target group.

Correct answer: B. People may become confused and take different actions

Explanation: The governing concept is consistency in multi-channel communication. When the same notice contains conflicting instructions, receivers cannot know which version to trust or what action is expected. They may follow different directions, causing errors, delay, or unfair results; therefore, option B is correct. Using several media does not automatically improve security or accuracy, and it never removes the need for feedback and clarification.

Correct answer: D. Verify through a reliable source and share a necessary correction

Explanation: The governing concept is responsible and accurate digital communication. Before forwarding a claim, a communicator should check it against a reliable source, consider possible harm, and correct misinformation when necessary. Thus, option D is correct. Immediate forwarding spreads an unverified claim, sensational wording increases harm, and closing all digital media is an unnecessary extreme rather than a responsible communication method.

Correct answer: A. Because actual reach is limited

Explanation: The governing concept is communication effectiveness, which depends on whether the intended receivers can actually access and understand the message. Speed and low cost are useful, but they cannot compensate when a large part of the target group is excluded. Therefore, option A is correct: actual reach is limited. Option B makes an unjustified claim about cost, option C about speed, and option D reverses the essential role of receiver access.

Correct answer: D. When fixing an important date and responsibility

Explanation: The governing concept is selecting an appropriate communication method. A verbal message is quick, while written confirmation creates a lasting record that can be checked later. Therefore, when an important date and responsibility are decided, writing the details reduces memory errors and disagreement. A greeting, joke, or informal introduction normally does not need such formal evidence.

Correct answer: B. Part of the message may be missed

Explanation: The governing concept is a listening barrier caused by divided attention. When a person mentally rehearses a reply throughout the speaker’s message, attention shifts from receiving and interpreting information to planning a response. As a result, important words, tone, evidence, or the actual question may be missed. Option B is correct. The other choices do not describe the normal effect of preparing a reply too early.

Correct answer: C. It lacks time-related clarity

Explanation: The governing concept is clarity in communication. The word “soon” is vague because different students may interpret it as today, tomorrow, or sometime this week. A clear message should state an exact date and, when necessary, a time. Therefore, option C is correct. The message is not necessarily too long or too formal, and no evidence shows that the communication medium itself is unsuitable.

Correct answer: C. Explain it using simple words or an example

Explanation: The governing concept is clarity through audience-centred communication and rephrasing. Repeating an unfamiliar technical term without explanation does not remove the barrier; it may only increase confusion. The speaker should define the term in simple language or connect it with a familiar example, so option C is correct. Speaking louder, ending the discussion, or blaming listeners does not improve understanding.

Correct answer: A. To strengthen recall and unity of the message

Explanation: The governing presentation principle is effective summarising. A brief review at the conclusion brings the central ideas together, reinforces the structure of the talk, and helps listeners remember the intended message after a long sequence of information. Therefore option A is correct. Adding unrelated material weakens focus, extending time is not the purpose, and a summary should not be used to prevent questions.

Correct answer: A. Genuine interaction

Explanation: The governing concept is two-way interaction in verbal communication. A presentation becomes genuinely interactive only when the speaker listens to audience responses, acknowledges them, and uses them to guide the discussion. Merely asking questions without receiving or responding to answers is one-way performance. Therefore, option A is correct; vocabulary, subject knowledge, and volume are separate qualities.

Correct answer: A. A live video meeting where participants respond immediately

Explanation: The governing concept is synchronous, or real-time, communication: the sender and receiver interact during the same period and responses are nearly immediate. In a live video meeting, participants can speak, listen, and reply without a planned delay, so option A is correct. A letter, prerecorded message, and delayed email are asynchronous because they can be accessed and answered later.

Correct answer: D. The message can be stored and received later

Explanation: The governing concept is asynchronous or store-and-forward communication. The sender can transmit the message without the receiver being online at that exact moment; the service may store it and deliver or display it when the device reconnects. Therefore option D is correct. Synchronous communication requires simultaneous participation, and the situation does not imply that the message is destroyed or that no network exists.
