One defining idea about empathy is that some aspect of it occurs automatically; people effortlessly mimic others' movements and actions, including facial expressions.

Evidence that this aspect of empathy may be biologically innate comes from the observation that children first show imitation of facial expressions

when they are explicitly instructed to do so.

in utero.

within the first few weeks of life.

when they start walking.

And your answer is?

The correct answer is "within the first few weeks of life". This evidence suggests that the ability to mimic facial expressions is biologically innate.

To arrive at this answer, we need to understand the concept of empathy and how it is related to the ability to mimic facial expressions. Empathy refers to the ability to understand and share the feelings of others. One aspect of empathy is the ability to mimic others' movements and actions, including facial expressions. This mimicry allows individuals to better understand and relate to the emotions of others.

Next, the question asks for evidence that this aspect of empathy is biologically innate. To determine this, we look for clues about when the ability to mimic facial expressions first emerges. The answer choice "when they are explicitly instructed to do so" suggests that the ability requires explicit instruction, which contradicts the notion of automaticity. The answer choice "in utero" refers to the time during pregnancy, which is too early for facial mimicry to occur. The answer choice "when they start walking" is unrelated to the development of facial mimicry.

Therefore, the correct answer is "within the first few weeks of life" because it suggests that infants begin to mimic facial expressions without explicit instruction shortly after birth. This aligns with the idea that this aspect of empathy is biologically innate.
