Earth's atmosphere blocks much of the light that astronomers need to observe distant stars. to get around this problem, nasa put a powerful telescope a) on mars. b) on the moon. c) in orbit around earth. d) in orbit around the moon.

The answer is;  C

By putting the Hubble telescope in orbit around the earth, they avoid most of the earth’s dense  atmosphere. The atmosphere causes a phenomenon referred to as atmospheric differential diffraction of light that is the reason we see stars as twinkling (yet they really don't twinkle). Avoiding atmosphere, therefore, improves image quality, reduces mirages, and reduces errors in observation.  

starchy vegetables are high in carbohydrates.

starchy vegetables contain more carbohydrates than non-starchy vegetables.

explanation:

there are two primary categories of carbohydrates, essentially differentiated on the basis of their carbohydrate content (which is in the form of starch - a complex carbohydrate):

those vegetables which contain little amounts of starch are termed as non-starchy vegetables, and some examples include: artichokes, broccoli and bean sprouts.

vegetables high in their starch content are distinguished as starchy vegetables, and some examples include: potatoes, chickpeas and corn.
