Methods of communication

Correct answer: D. Digital written communication

Explanation: The governing concept is the form and channel used to encode a message. A mobile text message consists of typed words or symbols and travels through a digital device or network, so it is digital written communication. Therefore, option D is correct. Audio and oral communication require spoken sound, while a visual sign alone does not fully describe a text message because the defining feature here is readable written language sent digitally.

Correct answer: A. Face-to-face oral communication

Explanation: The governing concept is immediate feedback in communication. In face-to-face oral communication, the speaker and listener are present together, so the listener can ask a question and the speaker can answer at once. A poster or printed book usually provides delayed, one-way information, while a one-way sign does not support a conversation. Therefore, option A is correct.

Correct answer: C. Audio signal communication

Explanation: The governing concept is the communication channel used to carry a message. A ringing bell produces a sound that people hear and interpret as a warning, so it is an audio or auditory signal. No written words, picture, letter, or visual symbol is required. Therefore, option C is correct, while options A, B, and D describe other channels.

Correct answer: B. Written message

Explanation: The governing concept is the form in which information is encoded. A handwritten note uses letters, words, and sentences written on paper, so the reader receives the message through written language. It is not heard like an audio message, spoken as an oral message, or primarily conveyed through a body movement. Therefore, option B correctly identifies it as a written message.

Correct answer: B. It can be stored for future reference

Explanation: The governing concept is permanence and record-keeping in written communication. A written message can be saved, reread, shared, and checked later, which is useful for instructions, notices, and evidence. It normally uses words, so option A is false; it must contain a message, so C is false; and it does not depend only on sound, so D is false. Hence, option B is correct.

Correct answer: D. Audio, video and chat

Explanation: An online meeting commonly combines several communication modes through a digital platform. Participants can speak and listen through audio, see people or shared material through video, and exchange written messages through chat. Thus option D is correct because it identifies the usual multimedia nature of an online meeting. Printed papers, letters and signs alone cannot provide the normal live interaction of such a meeting.

Correct answer: C. Visual communication

Explanation: Pictograms and symbols communicate their meaning through what people see, so they are examples of visual communication. Written communication mainly uses words and sentences, whereas a pictogram conveys meaning through a picture or sign. Exam tip: If a message is understood primarily by seeing it, classify it as visual communication.

Correct answer: B. Written communication

Explanation: Filling out a form involves entering names, dates, numbers or other information in written fields so that another person or organization can read and process it. Therefore option B, written communication, is correct. The completed form may be submitted digitally or on paper, but its communication purpose still depends on recorded written content. Oral, audio and visual-sign methods do not describe the main act.

Correct answer: C. Audio-visual

Explanation: The governing concept is the combination of sensory channels in communication. A video presents visible images, moving scenes or graphics while also carrying spoken words, music or other sounds. Since it can be both seen and heard, option C, audio-visual, is correct. Written and printed media are primarily viewed, while oral communication mainly depends on sound and does not necessarily include images.

Correct answer: B. Digital written communication

Explanation: The governing concept is the communication method determined by how a message is expressed. In a chat app, the sender types words, and the receiver reads them on a digital device. Therefore, it is digital written communication, so option B is correct. It is not only oral because no spoken sound is required, not non-verbal because words carry the message, and not radio communication because the exchange is text-based.

Correct answer: A. Written communication

Explanation: The governing concept is the recordable nature of written communication. When a message is written and preserved on paper or on a device, the receiver can return to it, check details, and read it again later. Thus option A is correct. A momentary gesture, an oral announcement, and a bell signal normally disappear after they are performed or heard, so they cannot be reread unless separately recorded.

Correct answer: C. Oral and non-verbal

Explanation: The governing concept is the combination of communication channels. Spoken words convey the verbal or oral part of the message, while hand movements, facial expressions, and posture convey non-verbal meaning. Therefore option C is correct. Writing, printing, and audio recordings are not necessarily involved when a person is speaking face to face with gestures, so the other combinations do not describe the situation accurately.

Correct answer: B. The message purpose and the receiver's need

Explanation: The governing concept is selecting a medium according to communication purpose and audience. The sender should consider what must be communicated, how urgent or detailed it is, and what the receiver can access and understand. Therefore option B is correct. Age alone, paper colour, or device price may sometimes matter, but none by itself determines whether a method will communicate the message effectively.

Correct answer: D. Sounding a siren or alarm

Explanation: A siren or alarm communicates an urgent warning quickly through a loud, attention-catching sound. It can alert many people at the same time, even when they are not reading a message. A long letter, a printed book, or an email sent after several days is too slow for an emergency. Thus, option D is correct.

Correct answer: A. Notice board and written message

Explanation: A notice board supported by a written message is suitable because the same date can be displayed clearly for many students to read. It also allows students to check the information again. Whispering to one student reaches only one person, while waiting or waving gives no dependable event details. Therefore, option A is correct.

Correct answer: D. The purpose of the message may not be understood quickly

Explanation: The governing concept is clarity in written communication. An email subject acts as a brief heading that tells the receiver what the message concerns. If it is vague or missing, the receiver must read further before identifying the purpose, so option D is correct. The email does not delete itself, become verbal, or necessarily lose its images; those choices describe unrelated effects.

Correct answer: A. Public announcement

Explanation: The governing concept is selecting a communication method according to audience size and reach. A public announcement uses a spoken message that can reach many people in the same place and at the same time, so option A is correct. A private message and a personal diary are intended for limited or individual use, while a silent signal may not provide enough information or reach the whole group.

Correct answer: D. The receiver will not understand essential timing information

Explanation: The governing concept is completeness in written communication. A notice should provide essential details such as what will happen, where it will happen, and when it will happen. Without a date and time, the receiver cannot know the schedule or may arrive too early, too late, or miss the event. Therefore, option D is correct; the other choices do not logically follow from omitting timing details.

Correct answer: A. When several steps must be understood quickly

Explanation: The governing concept is clear and organised written communication. Bullet points separate a procedure into visible units, allowing the reader to scan the instructions quickly, follow the correct order, and check whether each step is complete. Thus, option A is correct when several steps must be understood efficiently. Bullet points are not mainly used to hide emotion, obtain spoken feedback, or remove pictures, so B, C, and D are unsuitable.

Correct answer: D. Privacy may be breached and miscommunication may occur

Explanation: The governing concept is responsible digital communication: a sender must verify the recipient before pressing send. If a private message reaches the wrong person, confidential information may be exposed, and that person may misunderstand or misuse it. Therefore, option D is correct. The other options are incorrect because sending to the wrong person does not improve clarity, guarantee positive feedback, or make the medium faster.

Correct answer: A. Being clear, concise, and purposeful

Explanation: An effective message follows the principles of clarity, conciseness, and purpose. The receiver should understand the intended meaning without unnecessary words or confusion. Thus, option A is correct. A message does not become effective merely by being long, and it need not depend only on pictures. Preventing feedback can also leave misunderstandings uncorrected.

Correct answer: B. The receiver understood the message correctly and responded appropriately

Explanation: The governing concept is effectiveness of communication, which is judged by the result rather than by the length, loudness, or cost of a message. When the receiver understands the intended meaning and gives an appropriate response, the communication cycle has worked successfully. Therefore, option B is correct; the other choices are unreliable measures of success.

Correct answer: C. Face-to-face conversation

Explanation: The governing concept is two-way communication with immediate feedback. In a face-to-face conversation, the speaker can ask a question, the listener can answer at once, and both can clarify confusion through further exchange. Therefore, option C is correct. A newspaper and poster provide one-way information, while a recorded message cannot respond immediately to a new question.

Correct answer: B. Digital written communication

Explanation: The governing concept is the method or medium of communication. A timetable published on a website uses written words or symbols and is delivered through a digital platform, so it is digital written communication. Option A is incorrect because no spoken words are required. Option C is incorrect because the timetable is not mainly a gesture or body signal, and option D concerns communication through touch.

Correct answer: B. Ask for clarification

Explanation: The governing concept is clarity and feedback in effective communication. When a message has an unclear meaning, the receiver should ask the sender for clarification, such as a question or a specific explanation. This checks the intended meaning before a response is given, so option B is correct. Guessing can create an error, ignoring leaves the problem unresolved, and forwarding the message may spread the misunderstanding rather than remove it.
