Methods of communication

Correct answer: B. Broadcast or public digital notice

Explanation: The governing concept is matching the method to audience size and feedback needs. A broadcast or public digital notice distributes one consistent message rapidly to a very large audience without requiring a separate conversation with each person. Option B is correct. Private talks, handwritten letters and small-group discussions are slower, labour-intensive and better suited to limited audiences or two-way interaction.

Correct answer: C. Technical details are not expressed clearly and precisely

Explanation: The governing concept is selecting a channel that provides enough detail for the message's complexity. Emojis can express a simple feeling, but a technical problem usually requires the device, error message, time, steps already tried and the result. Option C is correct because emojis alone are too ambiguous for precise diagnosis. They are digital and may convey emotion, while the teacher can normally view them.

Correct answer: D. Clear written instructions and confirmation of understanding

Explanation: The governing concept is using redundancy and feedback for high-importance information. Dosage instructions can be misheard or forgotten, especially when spoken rapidly, so clear written directions provide a record and asking the patient to repeat or confirm them checks understanding. Option D is correct. Facial expressions, loud music and an unhelpful poster do not reliably communicate the exact dose or verify comprehension.

Correct answer: B. Sending a confidential message to the wrong group

Explanation: The governing concept is that written communication creates a durable record. Permanence is useful for timetables, examination instructions, and meeting minutes because those records can be checked later. However, if a confidential message is sent to the wrong group, the stored text may be copied, forwarded, or read by unintended people. Therefore option B is correct. The other examples show beneficial record-keeping rather than a clear disadvantage caused by permanence.

Correct answer: A. The receiver will struggle to understand relationships and priorities

Explanation: The governing concept is clarity and organization in written communication. Facts alone are not enough; headings, sequence, grouping, and emphasis help the receiver identify what is connected and what should be acted on first. Option A is correct because a disordered message increases cognitive effort and can cause the reader to miss relationships or priorities. It cannot make text more audible, guarantee immediate feedback, or change written language into non-verbal communication.

Correct answer: D. When students need to view the lesson at different times

Explanation: The governing concept is the difference between synchronous and asynchronous communication. A live video meeting requires participants to be present at the same time and is therefore suitable for immediate discussion or voting. A recorded video is asynchronous: learners can watch it at different times, pause it, and replay difficult parts. Option D is correct. The other situations specifically require live interaction, privacy, or an immediate shared decision.

Correct answer: B. It will take more time and the message may become inconsistent

Explanation: The governing concept is choosing an efficient communication method for the size of the audience. Repeating the same face-to-face explanation to many people consumes the sender’s time, and the wording or details may gradually change, producing inconsistent versions. Face-to-face communication does use words and normally allows feedback; it is also not always public. Therefore, option B gives both practical disadvantages and is correct.

Correct answer: A. Sentence meaning and boundaries may become unclear

Explanation: The governing concept is clarity in written communication. Punctuation marks separate sentences, clauses and ideas, helping the reader understand where one thought ends and another begins. Without commas, full stops or question marks, the same words may be interpreted in different ways. Therefore, option A is correct because missing punctuation can make meaning and sentence boundaries unclear. The other options do not logically follow: punctuation cannot make writing audible, guarantee an immediate reply or always reduce its length.

Correct answer: B. A step-by-step demonstration or video with brief instructions

Explanation: The governing concept is selecting a communication method that fits the nature of the content. A process involves movement, order and change over time, so a step-by-step demonstration or video can show what happens first, next and last. Brief written instructions reinforce the visual sequence. Option B is correct. An unsequenced paragraph, a bell sound and a single coloured symbol cannot adequately demonstrate the actions and order of a dynamic process.

Correct answer: C. Two-way exchange and diverse feedback will decrease

Explanation: The governing concept is balanced, two-way communication. A group discussion works when members both speak and listen, allowing ideas, questions, and feedback to circulate. If one person speaks continuously, others cannot contribute, so the exchange becomes less participatory and the group loses diverse viewpoints. Option C is correct; the other options do not logically result from dominating the conversation.

Correct answer: D. It is mainly one-way and offers limited immediate response

Explanation: The governing concept is choosing a communication method according to the required feedback speed and direction. A newspaper mainly distributes information from the organization to readers; readers cannot normally respond immediately through the same publication channel. Therefore it is weak for urgent two-way feedback. Option D is correct. Newspapers do contain written and visual material and can provide a lasting record, so A, B, and C are incorrect.

Correct answer: A. To prevent confidential information from reaching the wrong person

Explanation: The governing concept is confidentiality in secure communication. Before sending sensitive digital information, the sender should confirm that the intended recipient is genuine and authorized. This reduces the risk of disclosure, fraud, or accidental delivery to the wrong person. Option A is correct. Identity checking does not change a written message into speech, increase network speed, or improve image resolution, so B, C, and D are unrelated.

Correct answer: B. Visual appeal has overshadowed message completeness and clarity

Explanation: The governing concept is effective communication, which requires a message to be clear and complete, not merely attractive. Product conditions are essential information because they affect the receiver's understanding and decision. If decoration receives more attention than those conditions, visual appeal has overshadowed clarity and completeness. Option B is correct; the problem is not excessive feedback, an oral-only medium, or a small audience.

Correct answer: C. Add examples, visuals, and discussion with the definition

Explanation: The governing concept is selecting complementary communication methods for the receiver's understanding. A difficult abstract idea becomes easier when a definition is supported by a concrete example, a suitable visual, and discussion or questions. These methods address different ways of learning and allow clarification. Option C is correct. Making the definition harder, enlarging letters alone, or deleting the definition does not explain the concept more effectively.

Correct answer: D. The receiver will not know when the task must be completed

Explanation: The governing concept is completeness of instructions. A message may use simple, clear language and still fail if it omits an essential condition such as the deadline. Without that time limit, the receiver cannot plan the work or judge whether it was completed on time. Option D is correct. The missing deadline does not make the message non-visual, change its medium, or necessarily make its words unintelligible.

Correct answer: A. To choose a suitable and accessible medium

Explanation: The governing concept is audience analysis and accessibility. A communication plan should consider what the receivers understand, what technology they can use, and whether they need accommodations. This information helps the sender select a channel and format that people can actually access and interpret. Option A is correct. Making messages longer, removing feedback, or serving only the sender ignores the receiver and weakens communication.

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

Explanation: The governing concept is consistency in multi-channel communication. When the same announcement uses conflicting wording or instructions, receivers cannot tell which version is authoritative. They may interpret the message differently and take inconsistent actions, causing errors and reducing trust. Option B is correct. Using several media does not automatically improve confidentiality or accuracy, and it never removes the need for feedback; therefore A, C, and D are wrong.

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

Explanation: The governing concept is responsible and accurate digital communication. A claim that spreads quickly is not necessarily true, so it should be checked against a reliable source before further sharing. If it is false, a clear correction should be communicated so that group members can make informed decisions. Option D is correct. Forwarding unchecked information increases harm, making it attractive does not make it true, and deleting every message is unnecessary and unhelpful.

Correct answer: A. It is not effective alone because its reach is limited

Explanation: The governing concept is effective method selection: speed and low cost matter only when the intended receivers can actually obtain and understand the message. If 50% of the target group cannot access the method, its practical reach is incomplete, so it should not be used alone. Option A is correct; the other options wrongly treat cost or speed as the only criterion and ignore accessibility.

Correct answer: C. Receiver-centred medium selection

Explanation: The governing principle is receiver-centred communication: effectiveness depends not only on what the sender intends, but also on whether the receiver can access, understand, and use the message. Since the intention is clear but the medium is unsuitable, receiver-centred medium selection has failed. Option C is correct; message length, sender identity, and greeting do not address the central mismatch.

Correct answer: B. False information may spread rapidly

Explanation: The governing concept is responsible channel use and source verification. Speed can increase the reach of a crisis message, but an unidentified source makes its accuracy and authority difficult to check. Therefore false or misleading information may spread before correction, making option B correct. Formality, guaranteed receiver response, and record-keeping are not the primary risks described.

Correct answer: D. Excessive dependence on one medium

Explanation: The governing concept is planning for reach and receiver access. Important information should use a channel that the whole target group can reasonably receive; relying only on email excludes employees who do not check it regularly. Option D is correct. A written record, formal style, and sender identification may be advantages, but none fixes the accessibility gap. A second suitable channel could improve reach.

Correct answer: B. When confidential information is sent to the wrong receiver

Explanation: Written communication normally provides a useful record, but the same permanence can create a confidentiality risk. If confidential information is sent to the wrong receiver, it may be read, copied, or forwarded without permission. Thus option B is correct. Ordinary information, a clear heading, and correct spelling generally improve communication and do not themselves create the stated risk.

Correct answer: C. A video meeting followed by a written decision summary

Explanation: The governing concept is selecting complementary communication methods. A video meeting is synchronous, so participants can ask questions, clarify ideas, and make decisions immediately. A written decision summary is asynchronous and creates a durable reference for members who were absent or need to check responsibilities later. Therefore option C is best; a phone call lacks a shared record, while a poster or emojis cannot support detailed discussion.

Correct answer: D. Authenticity and control may become doubtful

Explanation: The governing concept is choosing an appropriate communication method and channel. An informal social group may allow forwarding, editing, misunderstanding, or access by unauthorised people, so the sender and the final version may become uncertain. Therefore, authenticity and control may be doubtful, making option D correct. Options A, B, and C incorrectly assume that informality automatically improves clarity, proof, or confidentiality.
