Question

★ which is the best way to combine sentences 5 and 6? a a typical sized baseball is 9 to 9.25 inches because a softball measures 12 inches. b a typical sized baseball is 9 to 9.25 inches since a softball measures 12 inches. c a typical sized baseball is 9 to 9.25 inches due to a softball measuring 12 inches. d a typical sized baseball is 9 to 9.25 inches while a softball measures 12 inches.

Explanation:

To combine sentences 5 and 6, we need to show the contrast or difference in ball sizes. Sentence 5 says a baseball is 9 to 9.25 inches, and sentence 6 says a softball is 12 inches. Option D uses "while" to effectively contrast the two sizes, making the relationship between the two sentences clear. Option A's "because" implies a causal relationship which is incorrect. Option B's "since" also implies a causal or reason - giving relationship which doesn't fit. Option C's "due to" is used to explain a cause, and the size of the softball is not a cause of the baseball's size. So the best option is D.

Answer:

D. A typical sized baseball is 9 to 9.25 inches while a softball measures 12 inches.
