On Improving Paragraphs problems on the SAT , you’ll encounter two common types of questions: sentence addition and sentence removal. While the two question types seem quite different, they are both testing you on logical flow in a paragraph. A sentence addition problem asks you to choose the sentence that can function has a smooth transition between two relatively disjointed sentences. Conversely, a sentence removal question asks you to remove a sentence that disrupts logical flow, often because it is digressive or irrelevant to the subject at hand. Let’s take a closer look at each type.

Sentence Addition
To understand sentence addition problems, you must understand the specific function of a sentence in context.
- Topic Sentences: To begin a paragraph, a topic sentence must adequately introduce the subject or purpose of the paragraph that follows. If asked to insert a sentence at the beginning of the paragraph, make sure you read the paragraph to understand the overall subject.
- Concluding Sentence: Each paragraph should end with a sentence that concludes (that is, summarizes or reflects upon) the content of the paragraph. The concluding sentence should also smoothly transition into the next paragraph, if one exists.
- Inside a Paragraph: If asked to insert a sentence inside a paragraph, make sure you read a few sentences above and below in order to grasp a sense of the paragraph’s logical direction. The inserted sentence should smooth over any lack of transition.
Sentence Removal
Sentence removal tests the same writing skills that sentence addition tests, but you are more likely to encounter irrelevant, digressive, or redundant sentences. These are sentences that either add unnecessary info or unnecessarily repeat info.
Here is an example of a sentence removal question. Below is a single paragraph taken from an essay which summarizes the plot of Stephen King’s The Stand:
Once they have found homes and organized committees to begin repairing the damage to the city, the people of Boulder begin to rebuild. (9) They find survivors with the training and knowledge to get the electricity, which had gone out when there weren’t enough people left to operate the power plants, running again. (10) This enables them to refrigerate food and use lights and appliances in their homes; these were the first steps toward returning to the “old” (i.e., pre-Apocalypse) ways of life. (11) The book subtly points out that the same progress that allowed humanity to live in such comfort and convenience before might eventually lead once more to society’s downfall. (12) Similarly, this theme is addressed in Marge Piercy’s novel Woman on the Edge of Time.
Example 1: Paragraph 2 could be most improved by omitting which of the following sentences?
A. Sentence 8
B. Sentence 9
C. Sentence 10
D. Sentence 11
E. Sentence 12
First, let’s try to identify the main function of this paragraph and the general shape of its logical flow. The paragraph continues the plot summary of the story. Here, we learn about the efforts of a group of people to rebuild after apocalyptic destruction. We learn about how the group reclaims lost technologies like electricity, but the speaker reveals the irony that these technologies may be more harmful than helpful in this post-apocalyptic civilization.
If you read each sentence in the answer choice, there should be one sentence that sticks out as irrelevant and distracting. Sentence 12, which inexplicably compares The Stand to another novel, problematically changes the logical flow of the paragraph and fails as an appropriate concluding sentence. Since the entire paragraph is only about The Stand, a sentence comparing the story to another is off topic, making the paragraph less effective as a cohesive unit. E is our correct answer.
