Let’s solve the questions one by one based on the reading passage about thunderstorms.
---
Question 1: What is the effect of a lightning flash?
From the text:
> “During a thunderstorm, electric charges in clouds flash as lightning, and lightning causes a sound wave we hear as thunder.”
So, when lightning flashes, it creates a sound wave — that’s thunder.
Looking at the choices:
a. electric outages → Not mentioned as a direct effect of lightning flash in this passage.
b. a sound wave we hear as thunder → YES! This matches exactly what the text says.
✔ Correct answer:
b

Question 2: What is the effect of a thunderstorm?
The text says:
> “Usually, there is strong wind and heavy rain as well. Thunderstorms can be very unsafe...”
Also, from earlier:
> “These three things cause thunderstorms to happen.” → So thunderstorms are the *result* (effect) of moisture, unstable air, and lift.
But the question asks for the *effect OF a thunderstorm* — meaning, what happens because of a thunderstorm?
From the text: strong wind, heavy rain, and being unsafe.
We need to write our own answer here since it’s open-ended.
Possible answer:
A thunderstorm causes strong wind, heavy rain, lightning, and thunder. It can also be dangerous, so you should stay inside.

Question 3: What should you do during a thunderstorm?
Text says:
> “Thunderstorms can be very unsafe, so it’s smart to stay inside until a storm ends.”
Choices:
a. Watch for tornadoes. → Not mentioned in the text.
b. Stay inside a house or car. → YES! Matches “stay inside” — and cars are safe too (though not stated, it’s common knowledge and fits).
✔ Correct answer:
b

Final Answer:
