Be sure your child wears sunscreen whenever she’s .......... to the sun.
پاسخ صحیح: گزینهٔ D — exposed
پاسخ تشریحی
Option 4: exposed. Be exposed to means to be in contact with, or subject to the effects of, something. A child who is “exposed to the sun” receives sunlight on her skin, which explains the instruction to wear sunscreen. Here “she’s” means “she is,” giving “she is exposed to the sun.”
| Option | Meaning | Why it fails |
|---|---|---|
| 1. demonstrated | Shown, proved, or illustrated | The sentence is about sunlight reaching the child, not someone showing or proving her. “Demonstrated to the sun” has no appropriate meaning here. |
| 2. confronted | Faced with a difficulty or challenge | The usual passive pattern is “be confronted with,” not “be confronted to.” It also does not express exposure of skin to sunlight. |
| 3. invulnerable | Unable to be harmed; immune to injury | “Invulnerable to” is a possible construction, but it would mean sunlight cannot harm her, undermining the reason for sunscreen. |
Check: “Whenever” introduces the recurring condition under which protection is needed: whenever sunlight reaches her skin.
Exam trick: Check both the preposition and the meaning. “Invulnerable to” fits the preposition but reverses the logic of the advice.
