Question

read the paragraphs and answer the questions that follow. the topic sentences appear in boldface.
body paragraph 1
dna sequencing is on the verge of revolutionizing the diagnosis and treatment of diseases—a revolution that spurs many ethical questions. first, dna sequencing is dramatically changing detection of diseases. currently, the detection of disease happens after symptoms appear in the tissues, organ, or bone where it originates. but now, some medical researchers are looking toward our dna.
body paragraph 1 ______ support the topic sentence effectively.
which revisions would include more supporting information or evidence? check all that apply.
☐ offer an example of a person whose disease was detected by a dna sequence test.
☐ this paragraph does not need more evidence.
☐ refer to a specific study on dna sequencing that shows how it is changing the detection of diseases.
☐ add testimony from experts about what dna sequencing is and how it can be used to detect disease.
☐ provide statistics on the percentage of people with cancer in the united states.

Explanation:

To determine which revisions add supporting info for the topic (DNA sequencing's role in disease diagnosis/treatment & ethical qs), we analyze each option:

• "Offer an example of a person whose disease was detected by a DNA sequence test": Examples of real - life cases where DNA sequencing detected disease directly support how it's changing disease detection.
• "This paragraph does not need more evidence": The paragraph currently has only a general statement about DNA sequencing changing detection. It lacks specific details, so more evidence is needed. Thus, this option is incorrect.
• "Refer to a specific study on DNA sequencing that shows how it is changing the detection of diseases": A specific study provides empirical evidence to back up the claim about DNA sequencing's impact on disease detection.
• "Add testimony from experts about what DNA sequencing is and how it can be used to detect disease": Expert testimony adds credibility and detailed information about DNA sequencing's role in disease detection.
• "Provide statistics on the percentage of people with cancer in the United States": This statistic is about cancer prevalence in the US, not about how DNA sequencing changes disease detection or treatment. It's irrelevant to the topic sentence.

Answer:

• Offer an example of a person whose disease was detected by a DNA sequence test.
• Refer to a specific study on DNA sequencing that shows how it is changing the detection of diseases.
• Add testimony from experts about what DNA sequencing is and how it can be used to detect disease.
