Question

which sentence best uses a split infinitive to clearly emphasize water safety?○ you will have to watch the children really at the beach because the current is very strong.○ you will have to really watch the children at the beach because the current is very strong.○ because the current is very strong, you will have to watch the children at the beach closely.○ because the current is very strong, to closely watch the children at the beach is something that one must do.

Explanation:

A split infinitive places an adverb between "to" and the base form of a verb. First, identify which option has this structure:

1. Option 1: "really" modifies location, not the infinitive "to watch".
2. Option 2: "really" sits between "to" and "watch" (to really watch), forming a split infinitive, and it emphasizes the urgent need to watch children for water safety.
3. Option 3: No split infinitive; "closely" follows the verb phrase.
4. Option 4: No split infinitive; "closely" precedes "watch" but not between "to" and the verb.

Only Option 2 uses a split infinitive to emphasize the critical water safety action.

Answer:

B. You will have to really watch the children at the beach because the current is very strong.
