12. As it is used in the last sentence of paragraph 2, pernicious means

Answer: B

Explanation:

Pernicious means harmful.

In the context of the extract, "pernicious" refers to the harmful nature of cervical cancer, which underscores the severity and destructive impact of the disease on Henrietta Lacks's life.

A) mild.

This option is incorrect because "mild" suggests a lack of severity or impact, which contradicts the context in which cervical cancer is described. The extract emphasizes that cervical cancer is a serious and destructive illness.

B) harmful.

This option is correct as it accurately captures the meaning of "pernicious" in the context of the extract. Cervical cancer is described as a particularly harmful disease that leads to significant suffering and ultimately death.

C) mysterious.

"Mysterious" does not align with the intended meaning of "pernicious." While cancer can sometimes be difficult to understand, the term "pernicious" specifically relates to the harmful effects of the disease, not its enigmatic qualities.

D) evil.

While "evil" can imply a sense of malevolence, it does not accurately reflect the medical context of the term "pernicious." The extract discusses the harmful impact of cervical cancer rather than attributing moral qualities to it.

Conclusion

The correct interpretation of "pernicious" as harmful is supported by the description of cervical cancer in the extract, which highlights its severe and life-threatening nature. All other options fail to capture the essence of the term as it relates to the negative effects of the disease, thereby reinforcing why "harmful" is the definitive choice.
