## Why these answers are right

**27. C.** The first paragraph reports Picard's case that a computer working closely with humans might need to sense emotional signals and respond to them. Detect and react to feelings is a close paraphrase of sense and respond, so C is correct.

**28. A.** In the second paragraph the writer says the driver monitoring market that Smart Eye supplies has been helped by law, then gives the EU requirement for drowsiness warnings as the example. The rule is offered as a cause of growth, which matches A.

**29. D.** The third paragraph says the combination was ideal for engineers because it gave a short list of categories to predict and a precise vocabulary for the evidence. A limited set of outcomes and an exact way of describing faces restates both halves, so D is right.
