Correct answer: A. Seeing everything but being unable to speak

Explanation: The governing concept is visual symbolism in social communication. In a poster, a feature may be enlarged or simplified so that it carries an idea beyond literal appearance. Large eyes can suggest awareness, witnessing, or seeing injustice, while a closed mouth can suggest silence, censorship, fear, or lack of power. Together they can communicate the condition of people who observe a problem but cannot speak openly about it, so option A is correct. Option B treats the image as a scientific lesson rather than a symbol; C describes measurement, not communication; and D is too narrow because the combination can convey a serious social message. The exact meaning depends on the surrounding text and imagery, but the proposed interpretation is the most coherent.

Correct answer: A. Importance of action or labour more than identity

Explanation: The governing concept is emphasis through selective clarity. Artists can make some parts sharp and leave others blurred so that the viewer’s attention moves toward the intended centre of meaning. Clear hands may highlight work, action, care, construction, service, or physical effort, while blurred faces can reduce the importance of individual identity. Option A is correct because the contrast can say that what people do matters more than who they are individually. B is not a sound interpretation unless the artwork provides evidence of concealment; C mistakes expressive emphasis for a fixed rule about size; and D is false because selective focus can communicate strong feeling. The meaning remains contextual, so posture, tools, repetition, and surrounding symbols should also be considered.

Correct answer: A. A green-biased blue and a blue-biased yellow

Explanation: The governing concept is subtractive pigment mixing and colour bias. To mix a bright green, choose a blue that leans toward green and a yellow that leans toward green; these pigments share the desired direction and introduce less unwanted red or orange influence. Therefore, option A is correct. Red-biased blue and orange-biased yellow tend to neutralise the mixture, while blue-red and yellow-violet pairs produce different or duller results.
