As children grow, their attention span:

Concept

For an explicit-statement reading-comprehension question, use the passage as the controlling evidence rather than outside assumptions.

Identify the sentence that addresses the asked relationship, then preserve its direction of change when matching it to an option.

Application

1. The passage says that young children have greater difficulty focusing and maintaining attention for long periods.

2. It then states that their attention will improve as they move through the elementary-school years.

Contrast

• Remains static would mean that attention shows no developmental change.

• Declines slightly would mean a small decrease in attention with growth.

• Declines significantly would mean a large decrease in attention with growth.

Cross-check

The passage links this development to continuing myelination in brain areas involved in focusing attention, which supports better focusing capacity with age.

Therefore, the answer is Improves.
