Answer 1

I don't have the passage you’re referring to. Could you paste the excerpt or summarize the main points?

If you want to decide on your own, here are quick clues to match each choice to textual cues:

- A (share true crime stories solved by DNA): look for multiple crime-case stories and emphasis on how DNA solved them — tone = narrative/true-crime.
- B (explain how microbial analysis can be used in forensic science): look for technical explanation of microbes, methods, how they link people/places — tone = explanatory/informative.
- C (argue microbial analysis is more effective than DNA testing): look for comparisons showing microbes outperform DNA, persuasive language, claims of superiority — tone = argumentative.
- D (acknowledge concerns surrounding forensic science): look for discussion of ethical/legal limits, reliability concerns, controversy, and balanced presentation — tone = cautionary/reflective.

Paste the passage and I’ll pick the best answer and point to the supporting lines.
