visual communication

The governing concept is accessibility in visual communication. A colour-only signal can be difficult for a person with colour vision deficiency because some colours may not be distinguishable. Thus option B is correct. Reading speed, height, and handedness do not normally affect the ability to interpret a colour-coded sign; adding text, symbols, or patterns would make it more inclusive.

The governing design concept is readability through contrast and visual simplicity. A complex background adds competing lines, colours, and details behind the letters, so the text boundaries become harder to see and read. Option D is therefore correct. A background does not automatically translate text, simplify its subject, or reduce the page size; those choices do not describe the communication failure.

The governing design concept is proximity, one of the principles used to organise visual information. Viewers usually assume that objects placed near one another are connected or belong to the same group, even when no line joins them. This reduces search effort and improves meaning. Proximity does not make items invisible, unrelated, or oppositional, so option C is correct.

The governing concept is presentation pacing and readability. A viewer needs enough time to see, read, and understand an important message. If the display changes before that process is complete, the message may be missed and the communication objective fails. Rapid changes do not make every message memorable or remove colour meaning. Therefore, option D is correct.

The governing concept is proportional use of a map scale. One centimetre represents 2 kilometres, so five centimetres represent 5 × 2 = 10 kilometres. The units are kilometres because the scale converts map centimetres into actual kilometres. Options B, C, and D result from incorrect operations or partial conversion. Therefore, option A is correct.

The governing concept is visual organisation and scannability. Dividing a poster into meaningful sections groups related information, creates a clear reading path, and helps viewers locate the part they need without searching through one crowded block. Sections may also improve hierarchy and comprehension. They do not hide messages, remove colour, or exist only to create empty space, so option B is correct.

The governing concept is accuracy and credibility in visual messages. Spelling errors make information appear careless or unreliable, even when the colours and layout look attractive. Thus the affected quality is credibility, making option A correct. Colour balance concerns relationships among colours, visual size concerns scale, and image proportion concerns shape or dimensions; none directly explains the loss of trust caused by errors.

The governing concept is typographic hierarchy. A title normally has greater size or weight than a subtitle so readers can immediately identify the main heading and supporting information. If both look identical, their relative importance is unclear; therefore option A is correct. The images do not automatically change meaning, the chart does not shrink, and equal text styling cannot make colours invisible.

The governing design principle is consistency. Repeating a controlled set of fonts, heading styles, spacing, and visual rules helps viewers recognise that slides belong to one presentation and locate information quickly. Changing the style on every slide creates visual inconsistency, distracts the audience, and weakens the presentation’s identity. It does not automatically improve colour contrast, data accuracy, or navigation. Therefore, option B correctly identifies the main problem.

The governing concept is colour contrast, specifically the difference in lightness or hue between foreground text and its background. When the two colours are nearly alike, the letter edges blend into the background and reading becomes difficult, even if the title is large. Increasing suitable contrast makes the words stand out. Symmetry, image proportion, and page size may affect layout, but they do not directly solve this readability problem; option C is correct.

The governing concept is sequential visual communication: when actions must be performed in order, the design must explicitly show progression. Numbers or directional arrows tell the viewer where to begin and which panel follows, reducing errors in the procedure. Therefore option D is correct. Texture, a decorative border and extra colour shades may change appearance, but they do not reliably communicate the required order.
