Answer: d No matter the amount of time or whether water is involved or not, sunburns can happen anywhere
Step-by-step explanation:
Even though there is no passage attached or referenced, this is most likely the answer.
Sunburns can indeed occur anywhere regardless of the presence of water or the passage of time which is why the first option speaks of activities involving water such as pool parties and activities that don't such as summer outdoor activities.
This is why it is necessary to protect yourself with sunscreen with the strength of the sunscreen dependent on where you are going for the summer activity. If adequate protection is not taken, a sunburn would be unavoidable.
