Verbal

Correct answer: A. Verbal communication

Explanation: The governing concept is verbal communication, in which ideas are conveyed through spoken language. When a teacher explains a lesson aloud, students receive the information by listening to the teacher’s words, so option A is correct. A classroom may also use a board, pictures, or gestures, but the action described is explaining through speech; therefore it is mainly verbal rather than only visual or written.

Correct answer: C. Non-verbal communication

Explanation: The governing concept is that non-verbal communication communicates meaning through body movement or behaviour rather than spoken or written words. A person can nod to show agreement without saying anything, so option C is correct. Written communication needs text, verbal communication uses spoken words, and telecommunication describes communication over distance rather than the specific form of the signal; the nod itself is a non-verbal gesture.

Correct answer: A. Verbal feedback

Explanation: The governing concept is verbal feedback within two-way communication. When a student asks a question aloud, the student responds to the teacher’s message and provides information about understanding or confusion. Therefore option A is correct. It may include facial or hand gestures, but the defining action in the question is spoken language; a written advertisement and printed news are unrelated written forms.

Correct answer: A. So the listener can understand the message easily

Explanation: Verbal communication depends on spoken words being heard and interpreted correctly. A clear voice, suitable pronunciation, and an appropriate speaking speed help the listener understand the intended message without unnecessary confusion. Clarity does not make a message longer, create a written record, or hide facial expressions. Therefore, option A correctly states the purpose.

Correct answer: A. When immediate discussion and response are needed

Explanation: Verbal communication uses spoken words and is especially useful when people need quick interaction. In an immediate discussion, the speaker can explain the idea, the listener can ask questions, and both can respond at once; therefore option A is correct. A printed message or letter may provide lasting evidence, while pictures suit visual communication, but neither is best for instant two-way discussion.

Correct answer: B. Public verbal communication

Explanation: In a school assembly, the principal addresses a group of students by speaking aloud. The communication is public because many listeners receive the same message, and it is verbal because spoken words carry the information. Thus option B is correct. It is not personal or private, and no letter or postal delivery is involved. The size of the audience and the spoken channel identify the type.

Correct answer: B. Verbal communication

Explanation: Communication delivered through spoken words is called verbal communication, so option B is correct. In this method, a speaker uses voice and language to send a message, and the listener may respond immediately. Written and printed communication use text on a surface, while visual communication mainly relies on images, symbols, or other visible signs. The defining clue is the act of speaking.

Correct answer: A. Through visual communication

Explanation: The governing concept is visual communication, in which information is conveyed through what the receiver sees. A map uses colours, lines, labels, shapes, and standard symbols to represent places, directions, distances, and physical features. Therefore, option A is correct. A map does not require speech, a telephone call, or gestures to communicate its basic geographic information.

Correct answer: B. To transmit voice

Explanation: The governing concept is verbal communication through a digital device. A microphone converts a speaker’s sound into an electrical or digital audio signal, which the meeting software sends to other participants. Thus, it enables the speaker’s voice to be heard remotely, making option B correct. A drawing tool creates pictures, a printer produces paper text, and facial expressions are non-verbal signals; none of these is the microphone’s function.

Correct answer: D. By hearing voice

Explanation: The governing concept is the communication medium through which a receiver understands a message. During a phone call, the receiver mainly uses hearing to understand the speaker’s voice, so the message is received through an audio or oral medium. Therefore, option D is correct. Pictures represent visual communication, written words represent written communication, and touch is a tactile method, none of which is the main channel in an ordinary phone call.

Correct answer: A. Oral communication

Explanation: The governing concept is verbal or oral communication, where spoken words carry the message from a speaker to listeners. During a speech, the speaker selects and says words aloud for an audience to hear and understand. A written script may support preparation, but delivering the speech itself is not only writing, touching, or showing pictures. Hence, option A is correct.

Correct answer: A. Speaking and listening

Explanation: The governing concept is oral or verbal exchange between a sender and a receiver. One person communicates by speaking, while the other understands the message by listening; effective oral communication generally requires both actions and may then include feedback. Drawing, writing a letter, or merely viewing signs uses other communication modes. Therefore, option A is correct.

Correct answer: A. Audio oral communication

Explanation: The governing concept is verbal or oral communication delivered through an audio channel. A loudspeaker carries a person’s spoken announcement as sound to listeners, so the message is heard rather than read, touched or viewed as a picture. Therefore option A is correct. Written communication would use words on paper or a screen, while touch and pictorial communication use different sensory forms.

Correct answer: A. Oral communication

Explanation: A group discussion mainly depends on participants expressing ideas, asking questions and responding by speaking and listening. This makes it a two-way oral communication process, so option A is correct. Written notes, pictures or signs may occasionally support the discussion, but they are not its principal method. The exchange of spoken viewpoints and immediate responses is the defining feature.

Correct answer: A. Oral communication

Explanation: A principal’s address is normally delivered by speaking to an audience, so the message reaches students through spoken language and sound. This makes it oral communication, and option A is correct. A written notice would be read, a pictorial message would depend mainly on images, and touch communication would use physical contact. None of those describes the main method of an assembly address.

Correct answer: D. Oral communication

Explanation: The governing concept is verbal or oral communication, where spoken words are supported by vocal features such as tone, pitch, stress, and speed. A friendly or angry tone can change how the same sentence is understood. Therefore option D is correct. Written, printed, and purely visual communication do not directly carry changing vocal tone, although punctuation or images may add other clues.

Correct answer: C. Audio oral communication

Explanation: The governing concept is the channel through which information reaches the receiver. An audio message carries spoken words or recorded voice, so the receiver understands it mainly by listening. Therefore option C is correct. It is not written or printed because the message is not primarily read, and it is not visual because pictures or diagrams are not the essential part of the communication.

Correct answer: C. Interest and attention may decrease

Explanation: The governing concept is effective verbal delivery, especially voice modulation. Changes in pitch, pace, and emphasis help listeners notice important ideas and maintain attention. Option C is correct because a continuous, unvaried tone can sound monotonous and cause listeners to lose interest or concentration. It does not create a recording, increase excitement automatically, or turn spoken content into visual communication.

Correct answer: C. It can be listened to again

Explanation: The governing concept is the difference between recorded and live communication. An audio recording preserves the speaker’s message, allowing the listener to replay difficult parts, review details and learn at a convenient time. Option C is correct. A recording necessarily contains sound and stores a message, but it does not automatically provide the immediate two-way response of a live conversation.

Correct answer: A. The language style does not match the context

Explanation: The governing concept is verbal communication adapted to context, audience, and purpose. A formal meeting normally requires clear, respectful, and suitably formal language. Excessive informal abbreviations may confuse listeners or make the speaker appear careless, so option A is correct. The fact that communication is oral or that the audience is present is not itself a problem, and meeting length does not explain the inappropriate style.

Correct answer: A. Words

Explanation: The governing concept is verbal communication, in which meaning is conveyed mainly through spoken or written words. Therefore, option A is correct. Pictures, signs, and colours can communicate visually or non-verbally, but they are not the defining channel of verbal communication. The key distinction is that verbal communication uses language, whereas non-verbal communication relies on cues such as images, gestures, facial expressions, and colour.

Correct answer: B. Oral communication

Explanation: The governing concept is that verbal or oral communication uses spoken words to share information. In a face-to-face conversation, both people communicate by speaking and listening directly, so oral communication is the best answer. Written communication requires text, visual communication depends mainly on images, and sign communication uses gestures or signs rather than ordinary spoken language.

Correct answer: C. Oral communication

Explanation: The governing concept is communication by spoken language. During a telephone call, the message is carried through a person’s voice and is received by listening, even though the telephone is used as a medium. Therefore, it is oral communication. Visual, written, and printed communication depend on seeing or reading words, images, or text, which is not the main process in an ordinary call.

Correct answer: D. Oral communication

Explanation: The governing concept is that oral communication conveys ideas through spoken words. When a teacher explains a lesson aloud, students receive information mainly by listening to the teacher’s speech. Thus, the example represents oral communication. Pictures may support the explanation, and writing may also be used in a classroom, but neither is the principal activity described in the question.

Correct answer: A. Language

Explanation: The governing concept is that verbal communication depends on language, including words and agreed meanings. A speaker selects language to form a message, and the listener uses knowledge of that language to understand it. Therefore, language is the essential element. Colour, shape, and symbols can support visual or non-verbal communication, but they are not the basic requirement of ordinary verbal communication.
