In which paragraph does the author describe an explanatory relationship?

a. It’s a difficult balancing act and, of course, parents get it wrong sometimes. After all, they’re only human too.

b. But it’s not always so easy. Children grow up so fast these days and it can be difficult to get it right all the time.

c. If they are too strict, their children might rebel. If they are too soft, then the children might only do the things they want to do.

d. For sure, parents know the importance of school and they want their children to do well, but what happens when the child doesn’t want to try?

e. Most parents want to do their best for their children and help them get ahead in life. They try to bring their children up well and give them a happy childhood.

Dear Doctor Clark,

I am writing to you about the serious threat of lionfish in the Atlantic Ocean.

a. We have already tested the first model, though it hasn’t been very effective so far.

b. Since then, we have been working on making a robot that will be able to kill lionfish with electricity.

c. Since 2004, the lionfish have been eating local fish, and they are continuing to destroy native species.

d. Until we can find a solution, we can only hope that the lionfish do not end up wiping out populations of native fish.

e. There are no natural enemies of the lionfish here, so we have been trying to train sharks to prey on them, but it didn’t work.

Your colleague,

Doctor Lewis
