visual communication

Correct answer: A. Data comparison may become incorrect

Explanation: The governing concept is clear labeling in visual communication. Row and column headings identify the categories, units, and conditions attached to each value. If those headings are unclear, a reader may assign a number to the wrong category or compare unlike quantities, so option A is correct. Attractive appearance, automatic sorting, or a need for more images does not logically follow from unclear headings.

Correct answer: A. Poor use of space

Explanation: The governing concept is layout and space management. A poster must balance images, text, margins, and the available page area so that every essential instruction remains visible. When an oversized image pushes important text beyond the edge, the space has been allocated poorly; therefore, option A is correct. The situation does not show correct priority, excellent readability, or a problem with choosing the symbol itself.

Correct answer: A. There will be confusion in identifying subjects

Explanation: The governing concept is consistent and distinct colour coding. A colour key works only when each colour reliably represents one category, or when repeated colours are supported by clear labels or patterns. Reusing one colour for several subjects makes the visual cue ambiguous, so option A is correct. It cannot change the timetable’s times, improve factual accuracy, or eliminate the need for text automatically.

Correct answer: A. Attracting immediate attention

Explanation: The governing concept is visual prominence, especially for safety-related information. A warning symbol must be large and clear enough to be noticed quickly before a person uses the product. If it is too small, it fails to attract immediate attention, so option A is correct. The size of the symbol does not increase the number of images, change the language, or determine whether the instruction is entertaining.

Correct answer: A. Simplify the shape and make it recognisable

Explanation: The governing concept is simplicity and scalability in visual design. A logo may appear on small screens, badges, stationery, or signs, so its essential form must remain recognisable when reduced. Removing unnecessary fine details and preserving a clear silhouette makes option A the best improvement. Adding more lines increases visual clutter, hiding parts reduces meaning, and a paragraph behind the logo does not solve the scaling problem.

Correct answer: A. The viewer may become confused

Explanation: The governing concept is relevance and coherence among visual elements. A picture should reinforce the title and intended message; when it is unrelated, the viewer must reconcile conflicting meanings and may misunderstand the poster. Thus, option A is correct. An attractive title alone cannot make the message accurate, an unrelated image does not become meaningful automatically, and image relevance does not directly improve text readability.

Correct answer: A. It becomes difficult to judge the reliability of the data

Explanation: The governing concept is context-aware data interpretation. A percentage describes a proportion, but its practical meaning depends on the base or total sample. For example, 50% of 10 people and 50% of 10,000 people do not provide the same strength of evidence. Without the sample size, judging reliability and significance is difficult, so option A is correct. The other choices are unrelated design effects.

Correct answer: A. Inconsistent colour meaning

Explanation: The governing concept is consistent colour coding, especially in safety communication. Red should not simultaneously represent a safe route and a hazard because these meanings conflict and can cause a person to choose incorrectly during an emergency. Therefore option A is correct. White space, image quality, and symmetry may affect appearance, but they do not create this specific semantic ambiguity.

Correct answer: A. Mismatch between audio and visual messages

Explanation: The governing concept is multimodal alignment: narration and visuals in an educational resource should communicate the same idea. Rotation means Earth spins on its axis, whereas revolution means it moves around another body; showing the latter while saying the former can teach an incorrect concept. Duration, colour choice, and title placement do not explain the contradiction. Hence, option A is correct.

Correct answer: A. What information outside the frame has been removed?

Explanation: The governing concept is visual literacy and contextual reading. Cropping selects what the audience sees and can change the apparent meaning or emotional effect of an event. A careful viewer should therefore ask what information, people, or surrounding circumstances were removed outside the frame before accepting the implied message. Counting colours, identifying the camera brand, or measuring the border does not test whether the presentation is complete or misleading.

Correct answer: C. The darker shade represents a larger value

Explanation: The governing concept is a visual encoding convention: changes in colour intensity are often assumed to represent changes in quantity or importance. Without a legend, viewers may apply the familiar assumption that a darker shade means a larger value, even though this graphic uses the reverse scale. Thus option C is the likely incorrect conclusion. A legend would explain the actual light-to-dark relationship and prevent misreading.

Correct answer: A. Viewers may interpret thickness as importance or quantity

Explanation: The governing concept is visual encoding: a visible difference is normally interpreted as carrying information. When arrow thickness varies without a legend or explanation, viewers may reasonably infer that thicker arrows represent greater quantity, strength, importance, or flow. That unsupported inference creates ambiguity and can lead to a wrong reading of the diagram. The variation does not automatically change the text, topic, or dimensionality.
