Masja [62]
<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.

notka56 [123]

Also, the majority of the countries have very close ties when it comes to economy and culture, and as mentioned this is easily noticeable when it comes to countries that are bordering.

Because there are cultural similarities, as well as economic ties, the people tend to known at least one more language apart from their native language, or in some cases the people tend to know multiple languages.

It also has to be taken in consideration that the English language is usually the international language in Europe, so more and more people across the continent speak it, and the learning of the language starts since early childhood.
