Combining Sentences Exercise (630)

For each pair or group of sentences, reorganize the statements into one sentence by converting one or two sentences into subordinate clauses of the remaining sentence.

Answers and Explanations

1.
Original: The thalamus feeds into the brain’s limbic system. The limbic system resembles the shell of an egg around the thalamus and the corpus callosum.
Correct : The thalamus feeds into the brain’s limbic system, which resembles the shell of an egg around the thalamus and the corpus callosum.

The repetition of the phrase "limbic system" at the beginning of the second sentence immediately after its use at the end of the previous sentence is clumsy. To smooth out of the sentences, replace the subject of the second sentence with the pronoun "which" and change the intervening punctuation from a period to a comma.

2.
Original: Disease-fighting lymphatic tissue in the gut has its own name, gut-associated lymphoid tissue, or GALT. GALT is key to digestive health.
Correct : Disease-fighting lymphatic tissue in the gut has its own name, gut-associated lymphoid tissue, or GALT, which is key to digestive health.

These sentences can be combined just like the ones in the first example. Here, in addition, the parenthetical phrase "or GALT" could be changed to "GALT" in parentheses, with the first of the pair of commas and the "or" omitted.

3.
Original: The cells that consume neutrophils and coordinate the serious business of healing are called macrophages. "Macrophage" means "big eater." Macrophages live in the blood as cells called monocytes.
Correct : The cells that consume neutrophils and coordinate the serious business of healing are called macrophages ("macrophage" means "big eater"), which live in the blood as cells called monocytes.

This sentence suffers from two additional repetitive references to the term that ends the first sentence. The third reference can be altered as it was in the previous examples, and the parenthetical middle sentence can become a literally parenthetical statement by being enclosed in parentheses.

4.
Original: The founder is busy checking the books and preparing for upcoming fund-raisers. She is hopeful that the plan to turn the programs over to locals in one to two years can be kept on track.
Correct : The founder, busy checking the books and preparing for upcoming fund-raisers, is hopeful that the plan to turn the programs over to locals in one to two years can be kept on track.

Here, the predicate of the first sentence is converted to a parenthetical phrase, and the subject of the second sentence is deleted to allow the predicate to become the second half of the main clause.

5.
Original: The study was flawed. As a result of this, the study was rejected for publication.
Correct : Because the study was flawed, it was rejected for publication.

The first sentence can be folded into the second one as a subordinate clause.
