Which sentence provides the best concluding statement for this passage?
In conclusion, stay indoors.
In short, brief exposure to indoor tanning may be acceptable, it is not
preferable.
Lastly, indoor tanning salons are expensive; save your money and spend
more time outdoors.
The best course of action is to avoid indoor tanning and apply sunscreen
before spending the day outside.
Judging by the sentences themselves, I would say the last sentence is the best concluding statement. However, I don't have the passage, so I can't 100% percent give you my opinion on the best concluding statement for your passage. (:
