non-verbal

Correct answer: D. Friendliness or happiness

Explanation: The governing concept is non-verbal communication, in which facial expressions convey meaning without spoken or written words. A smile commonly signals friendliness, pleasure, welcome, or happiness, although its exact meaning can depend on context. It cannot itself be a long written message, radio news, or a mathematical formula. Therefore, option D is correct.

Correct answer: D. Hand signs and facial expressions

Explanation: The governing concept is visual, non-verbal communication. Sign language conveys words and ideas through structured hand shapes, movements, positions, and facial expressions that the receiver observes. It does not mainly depend on printed news, radio waves, or written letters alone. Although some sign systems have their own linguistic rules, the relevant school-level answer is the visible use of hand signs and facial expressions, option D.

Correct answer: C. Gestures, posture and facial expressions

Explanation: The governing concept is non-verbal communication, in which meaning is conveyed without spoken or written words. Gestures, posture, facial expressions, eye movement and body position can express feelings, attitude or intention. Therefore, option C is correct. Books, emails and speeches mainly depend on written or spoken words, so they do not represent the best answer here.

Correct answer: D. Showing a thumbs-up gesture

Explanation: Non-verbal communication conveys meaning without spoken or written words. A thumbs-up is a recognizable gesture that can communicate approval, agreement or encouragement, so option D is correct. Writing a letter and sending an email use written language, while giving a speech uses spoken language. Those alternatives are verbal forms even though their delivery methods differ.

Correct answer: D. Non-verbal communication

Explanation: Eye contact is a non-verbal signal because it communicates attention, confidence, interest or respect without using words. Its meaning depends on the situation and culture, but it is an important part of body language and face-to-face interaction. Therefore option D is correct. Written communication, newspapers and radio broadcasts do not depend on eye contact to transmit their messages.

Correct answer: D. Through an audio signal

Explanation: The governing concept is non-verbal communication through a conventional sound signal. The bell produces a recognizable sound, and students learn that this sound means the period or school day has ended. Therefore option D is correct. No written paragraph, facial expression, or picture is necessary for the message. The meaning comes from the agreed association between the bell’s sound and dismissal.

Correct answer: A. Attention and confidence

Explanation: The governing concept is non-verbal communication and body language. In a face-to-face conversation, suitable eye contact generally shows that a person is attentive, engaged, and reasonably confident. Therefore, option A is correct. Eye contact does not create a permanent record, measure internet speed, or prove the accuracy of written language; those options belong to different communication features.

Correct answer: B. Upright, relaxed, and confident

Explanation: The governing concept is non-verbal communication through body language. In a formal presentation, an upright but relaxed posture suggests confidence, readiness, and respect for the audience without appearing stiff. Option B is correct. A bent posture may suggest uncertainty, turning away breaks engagement, and constant movement distracts listeners from the message.

Correct answer: C. Smiling and maintaining suitable eye contact while praising someone

Explanation: The governing concept is congruence between verbal and non-verbal communication. When a person praises someone while smiling and maintaining suitable eye contact, the facial expression and gaze support the positive spoken words, making the message warmer and more credible. Option C is correct. Laughing during an apology or showing anger while agreeing creates contradiction, while turning away during a welcome weakens the intended friendliness.

Correct answer: C. Smiling and maintaining suitable eye contact while praising someone

Explanation: The governing concept is consistency between verbal and non-verbal communication. Praise is a positive oral message, and a genuine smile with suitable eye contact supports that meaning by showing attention and goodwill. Therefore, option C is correct. Looking away suggests disinterest, laughing can weaken an apology, and an angry posture conflicts with agreement, so those cues do not reinforce the spoken words effectively.

Correct answer: A. Spoken words

Explanation: Non-verbal communication conveys meaning without spoken words, using channels such as facial expressions, gestures, posture, eye contact, and body movement. Thus option A is correct. Facial expressions, gestures, and posture are all common forms of non-verbal communication, so options B, C, and D are examples rather than what is absent.

Correct answer: B. Non-verbal communication

Explanation: The governing concept is non-verbal communication, which conveys meaning without relying on spoken or written words. A smile uses a facial expression to communicate friendliness, happiness, or approval, so option B is correct. Written, oral, and printed communication all depend mainly on words or text, unlike this facial cue.

Correct answer: D. Attention and confidence

Explanation: Eye contact is a non-verbal communication cue. In an appropriate social or classroom situation, looking at the speaker generally suggests that a person is attentive, engaged, and reasonably confident; therefore option D is correct. Eye contact is not proof of confidence in every culture or situation, and continuous staring can be inappropriate.

Correct answer: A. Emotions

Explanation: Facial expressions are non-verbal signals produced by changes in the face, such as smiling, frowning, or raising the eyebrows. They can reveal emotions including happiness, sadness, surprise, or concern, so option A is correct. Spelling, writing style, and a book title are represented through written language, not facial movement.

Correct answer: B. Body language

Explanation: The governing concept is body language, a part of non-verbal communication in which posture, gestures, and body position convey meaning. Folding the arms is a visible posture, so option B is correct. Pronunciation uses speech sounds, writing uses text, and an oral presentation is a spoken performance; none specifically describes the arm position itself.

Correct answer: D. A non-verbal message

Explanation: Communication does not always require spoken words. Silence can function as a non-verbal message when the surrounding situation gives it meaning, such as showing disagreement, hesitation, respect, or unwillingness to answer. Therefore option D is correct. It is not automatically writing, reading, or dictionary practice; interpretation depends on context and the relationship between speakers.

Correct answer: A. Approval

Explanation: A thumbs-up is a gesture, so it communicates through body movement rather than through spoken or written language. In many everyday contexts it generally expresses approval, agreement, or that something is good, making option A correct. It does not normally mean anger, fear, or tiredness, although gestures can have different meanings in particular cultures or situations.

Correct answer: B. Confidence

Explanation: Posture is a non-verbal communication cue because the way a person holds the body can influence how others interpret attitude and readiness. An upright, balanced posture generally suggests confidence, alertness, and engagement, so option B is correct. Carelessness, sleepiness, and uncertainty are not the usual meanings of standing straight, although context should always be considered.

Correct answer: C. Touch cue

Explanation: A handshake communicates through physical contact, so it is specifically a touch cue and the correct answer is option C. It is also a form of non-verbal communication because spoken or written words are not required for the gesture itself. A verbal cue uses words, a written cue uses text, and an audio cue depends on sound rather than touch.

Correct answer: D. Concern or displeasure

Explanation: Frowning is a facial expression and therefore a non-verbal cue. In many ordinary situations, drawing the eyebrows together may indicate concern, displeasure, concentration, or discomfort; among the given choices, option D is the best answer. Happiness and excitement are more commonly associated with smiling, while relaxation is not usually shown by a frown. Context can change the exact interpretation.

Correct answer: A. Sound signal

Explanation: The governing concept is non-verbal communication: a message can be conveyed without spoken or written words. A school bell uses sound to announce a period change, assembly, break, or another event. Therefore, option A, sound signal, is correct. A written message needs text, while a facial expression and hand gesture are visual bodily cues rather than the bell’s medium.

Correct answer: C. A wish to speak or answer

Explanation: The governing concept is a non-verbal classroom signal. Raising a hand commonly communicates that a learner wants the teacher’s attention, permission to speak, or an opportunity to answer. Therefore option C is correct. It does not normally mean leaving the class, feeling sleepy, or closing a book; those choices do not explain the established classroom gesture.

Correct answer: D. Personal space

Explanation: The governing concept is proxemics, or the non-verbal use of physical distance in communication. The space maintained between a speaker and listener can express comfort, formality, privacy, or discomfort. Therefore option D, personal space, is correct. Spelling, vocabulary, and pronunciation concern language form or speech sounds, not the physical distance between communicators.

Correct answer: A. Smile

Explanation: The governing concept is facial expression as non-verbal communication. A smile is widely used to show happiness, warmth, friendliness, or pleasure, so option A is correct. Frowning is more often associated with displeasure or concern, turning away may suggest avoidance, and closing the eyes has many possible meanings and is not a clear general sign of happiness.

Correct answer: B. Hurry or impatience

Explanation: The governing concept is interpreting non-verbal cues in context. Repeatedly checking a watch may suggest that the listener is in a hurry, impatient, or concerned about time; therefore option B is the best answer. It is only a possible indication, not proof. A single gesture should be considered with facial expression, words, and the surrounding situation.
