<h2>
Answer: C) stars in these regions are hidden by interstellar dust grains.</h2>
Explanation:
Some areas of the Milky Way seem dark because those are areas of the galaxy that are hidden by huge columns of interstellar dust that we cannot see through the visible range of the electromagnetic spectrum (which is the range in which our eyes see).
However, to solve this problem, astronomers use telescopes that work in the range of infrared and radio waves, to observe a little more through this intersetelar dust.

Agricultural consumption refers to the consumption, or eating, of a place's agriculture, or farmed resources, such as wheat, hay, crops, etc. However, it may also refer to the "using up" of a place's resources. For example, take the phrase, "The economy consumed the country's resources." The economy didn't actually eat the resources, but used them up. Either works depending on the situation, but most likely, the question is looking for the first answer :)
