Understanding Vocabulary and Sentence Completion
This question asks us to choose the most suitable word to fill the blank in the sentence: "Stress may ________ fertility in men and women." We need to select a word from the given options that makes the sentence grammatically correct and meaningful in the context of how stress affects fertility.
Analyzing the Options for Stress and Fertility
Let's look at each option and consider its meaning:
- Engage: This word usually means to participate in an activity or attract attention. For example, "engage in a conversation" or "the story engaged the readers." Stress doesn't "engage" fertility; it doesn't participate in it or attract it.
- Reduce: This word means to make something less in amount, size, or degree. For example, "reduce stress" or "reduce the price." In the context of health, stress is known to have negative effects, often making bodily functions less effective or lowering levels of something. It makes sense that stress could make fertility lower or less effective.
- Inject: This word means to force a liquid into something, often with a syringe, or to introduce something into a situation. For example, "inject medicine" or "inject humor into a speech." Stress doesn't "inject" fertility.
- Deduce: This word means to arrive at a conclusion by reasoning. For example, "deduce the answer from the clues." Stress doesn't "deduce" fertility; it's not a logical process.
Determining the Most Appropriate Word
Considering the negative impact that stress often has on biological processes, the word that best describes how stress affects fertility in a negative way is "reduce." Stress is widely understood to potentially lower the chances of conception or impact the health of reproductive systems, thus reducing fertility.
Therefore, the sentence "Stress may reduce fertility in men and women" is the most logical and commonly accepted statement.
