Question

What is the BEST way to revise this sentence so that it conveys clear, concise ideas and does not change the meaning of the sentence?

Astronomy is the study of the sky that is all around us and the study of the mysterious objects in the vast reaches of space.

Question 5 options:

Astronomy is the study of the sky.


Astronomy is the study of mysterious objects.


Astronomy is the study of the sky that is all around us.


Astronomy is the study of the sky and the mysterious objects in it.

Answer 1

Astronomy is the study of the sky and the mysterious objects in it

Answer 2

Astronomy is the study of the sky and the mysterious objects in it.

Step-by-step explanation:

When you read the first sentence you have two principal ideas:

Astronomy is te study of the sky.

Astronomy studies the misterious objects in the space.

So now all the other words in that sentece make the sentence more beautiful but at the same time can create confusion, since there is no sky that is not around us, we can get rid of that, since that is not vital, and since in the term sky it´s involved the reaches of space we can get rid of that too, so we can create:

Astronomy is the study of the sky and the mysterious objects in it.

Which says basically the same, in a simpler way.
