1. Which of the following sentences is best to include in a summary of the text?

Answer: B

Explanation:

Walking intermittently during a run can reduce fatigue and increase performance.

This statement encapsulates a key strategy that is beneficial for runners, particularly in the context of endurance and performance which aligns with the challenges discussed in the extract regarding long-distance running.

A) Long-distance running involves arduous training plans that can result in soreness.

While this option discusses the challenges of long-distance running, it does not directly relate to strategies for improving performance or reducing fatigue, which are central to the extract’s focus. Thus, it fails to capture the essence of an effective summary.

B) Walking intermittently during a run can reduce fatigue and increase performance.

This option is the best choice as it highlights a specific technique that can enhance performance in long-distance running, directly addressing the need for effective strategies mentioned in the extract. It aligns with the overall theme of improving endurance and managing fatigue.

C) It is important to have a strategy when training to run long distances.

Although this statement is relevant to the topic of training, it is too general and does not specify any particular strategy. The extract emphasizes specific methods, such as walking intermittently, which makes this option less effective as a summary.

D) Mental confidence helps to overcome challenges that come with running.

This option introduces a psychological aspect of running but does not address the physical strategies necessary for performance enhancement. It diverges from the practical focus of the extract, making it an inadequate summary choice.

Conclusion

The correct answer, B, effectively summarizes a specific approach to improving long-distance running performance by incorporating walking, which can alleviate fatigue. The other options, while related to running, fail to provide a focused strategy or actionable insight as described in the extract. Hence, B stands out as the most relevant and precise choice for summarizing the text.
