Question

select the correct text in the passage.
which sentence explains why optical land telescopes are not able to take images as clear as those taken by the hubble space telescope?
hubble and land telescopes take pictures of planets, stars, and galaxies. the mixture of gases that surround a planet is called its atmosphere. earths atmosphere changes and blocks some of the light that comes from space.
hubble needs to be updated.
so, hubble can see space more clearly than telescopes on earth can. hubble is not the kind of telescope that you look through with your eye. hubble uses a digital camera to take pictures. then, hubble uses radio waves to send the pictures through the air back to earth.

Explanation:

We need to find the sentence that explains why optical land telescopes can't take as clear images as Hubble. The key is to look for a reason related to Earth's conditions affecting light. The sentence "Earth's atmosphere changes and blocks some of the light that comes from space." directly gives this reason.

Answer:

Earth's atmosphere changes and blocks some of the light that comes from space.
