9.1–9.4 and conjunctions. Sometimes there is more than one way to correct an error.

know? Lightning.
Did
you

because/since
1. We do not see most lightning even though it happens inside
clouds.

2. Lightning usually strikes near the center of a storm, because

it can also strike far from the center.

3. Rubber shoes do not protect people from lightning, and so
do small buildings.

4. Lightning can travel through wires, although it’s dangerous
to use electrical equipment during a storm.

5. Lightning doesn’t just happen during thunderstorms. People have seen lightning

during forest fires, snowstorms, but volcanic eruptions.

6. Many people believe that lightning never strikes in the same place twice, so that
is not true. Keep away from places that attract lightning.
