Each of the following sentences in this section has a blank space and is followed by four choices. Select the most appropriate choice to fill in the blank.
Reading ability in young children________ by speech disorders.

Correct option is D

"Is affected" is the correct passive voice construction for the sentence, indicating that the "Reading ability" (subject) undergoes an influence by "speech disorders" (agent). In English, passive voice is often used to highlight the action's effect on the subject, especially when the agent is either unknown or less important than the action itself.
