Question #N1265

A new study shows that people who spend more time in nature report feeling happier and more creative. In fact, spending time in green spaces can help reduce stress and anxiety. However, some experts argue that these benefits are exaggerated, and that the true source of happiness and creativity might be found in other activities, such as spending time with friends and family, or engaging in creative pursuits.

Which of the following is the most effective way to combine the sentences in the underlined portion of the passage so that the passage conforms to the conventions of Standard English?
A. In fact, spending time in green spaces can help reduce stress and anxiety, however, some experts argue that these benefits are exaggerated.
B. In fact, spending time in green spaces can help reduce stress and anxiety; however, some experts argue that these benefits are exaggerated.
C. In fact, spending time in green spaces can help reduce stress and anxiety, some experts argue that these benefits are exaggerated, however.
D. In fact, spending time in green spaces can help reduce stress and anxiety, but some experts argue that these benefits are exaggerated.

Correct Answer is: D

Choice D is the best answer because it uses a comma plus the conjunction "but" to correctly combine the two main clauses. This creates a grammatically correct sentence that logically connects the two ideas expressed in the sentence.
