Question 35

Lightning consists of a main stroke and several smaller strokes.

Lightning is actually a series of events that includes a leader stroke followed by as many as 40 smaller strokes that occur in quick succession. This understanding contrasts with the misconception that lightning consists of a single stroke.

A) Always consists of a single stroke

This option is incorrect because the extract clearly states that lightning consists of a leader stroke followed by multiple smaller strokes. The idea that lightning is solely a single event is a common myth.

B) Is harmless and does not pose any risk

This option is also incorrect. The extract mentions that lightning causes injuries, deaths, and forest fires each year, indicating that it is indeed dangerous and poses significant risks to life and property.

C) Consists of a main stroke and several smaller strokes

This statement is correct as it aligns with the information provided in the extract. Lightning is described as having a leader stroke followed by numerous smaller strokes, which is a crucial aspect of its nature.

D) Only occurs during thunderstorms

This option is misleading. While lightning is most commonly associated with thunderstorms, the extract does not limit its occurrence to these conditions, and it implies that lightning can form under various atmospheric conditions.

Conclusion

The correct answer is option C, as it accurately reflects the nature of lightning as described in the extract, highlighting its complex structure of a main stroke followed by several smaller strokes. Options A, B, and D fail to capture the essential characteristics of lightning, while C provides a clear and factual understanding of this natural phenomenon.
