Question

Read the passage from "Cool Jobs Part 1."

One issue is that the science of analyzing microbial DNA is still imprecise. Imagine giving the same set of microbe samples to four groups of
researchers, Eisen says. You'd think that each group would find similar populations of germs. But that's not what happens. Their results can
vary a lot, depending on who does the analysis. He says, "You should be very skeptical of using [such a technique] in an investigation where
someone's life and safety and future freedom is at stake."
How do the descriptions "the science of analyzing microbial DNA is still imprecise" and "You should be very skeptical contribute to the tone of this
Dassage?
Cool Jobs Part 1

Answer 1

The descriptions "the science of analyzing microbial DNA is still imprecise" and "You should be very skeptical" contribute to a skeptical and cautious tone in the passage. The author is suggesting that the science of analyzing microbial DNA is not yet reliable enough to be used in investigations where the stakes are high, such as those involving people's safety and freedom. The tone suggests that there is a lot of uncertainty and potential for error in this field, and that caution is needed when interpreting results.

Step-by-step explanation:

Answer 2

They contribute to the tone of this passage, option d, they provide a cautionary tone because they describe that forensic results are still inaccurate.

They contribute to a cautionary tone by highlighting the imprecision and urging skepticism in relying on forensic results based on microbial DNA analysis.

The descriptions "the science of analyzing microbial DNA is still imprecise" and "You should be very skeptical" contribute to a cautionary tone in this passage. They emphasize the uncertainties and limitations within forensic discoveries based on microbial DNA analysis, urging skepticism and highlighting the potential risks involved when relying on such techniques in critical investigations. This cautionary tone underscores the need for prudence and wariness due to the current lack of precision in these methods.
