Lydia has reread a paragraph several times and still does not understand what is happening in the story.

Lydia should try to

use a strategy, such as making a mental picture of the paragraph’s events.
keep going until she gets to the end of the entire book.
reread the paragraph three more times.
ask herself, “Does this make sense?”

A). Use a strategy, such as making a mental picture of the paragraph’s events.

Explanation:

Visualization(as a reading strategy) assists the readers to engage personally in the text through mental images that allow them to have a sense of ideas, situations, or characters that are being discussed which plays a vital role in their effective and comprehensive understanding of the text.

In the given situation, Lydia is supposed to employ a strategy, like visualizing that involves 'making a mental picture of the events or ideas described in the paragraph' as it would assist her in having a sensory experience(through her imagination and visualization) of the situation that would help her connect to the story and encourage her to have a thorough understanding. Therefore, option A is the correct answer.
