Answer:
The most likely explanation is that the star is a member of an eclipsing binary star system.
Explanation:
An eclipsing binary star system takes place when two stars which are close to each other move in an orbit in which sometimes, one star can hide the light behind the other.
There are two types of eclipses depending on the orientation of the orbit and the size of the stars: the totals or the annular ones. It may also be the case that the eclipses are partial.
<em>Algol </em>is the best known eclipsing binary star, and the first of this kind to be discovered. Its interval between eclipses is 173 hours (2.9 days).
When this type of eclipses happens, the brightest star provides 92% of the light of the system, while the eclipsed only contributes less than 8%, and there is a third star, which is not eclipsed.
Therefore, if there is any star that has been bright most of the time, and during certain time intervals it becomes dimmer, that star is being overshadowed.
The correct answer is - A famine in Ireland prompts US response.
With the Irish famine of the 19th century, and the response to it by the United States, we have a very nice example of domestic influence on foreign policy.
Namely, the Irish potato famine was so bad, that very large percentage of the Irish population actually died, and the rest of the population was on the verge of starvation. Because of this, lots of people wanted to move out of the country in order to at least be able to have food on the table. This prompted a response from the United States, and they made an exception in their strict foreign policy because of the Irish people, so opened their borders to them in order to help them, thus letting them settle in the country.
The correct option is LOESS.
Loess refers to a compacted yellowish deposit of wind blown sediments which is usually found extensively in the mid latitudes. Loess is formed by the accumulation of dust that had been blown by the wind. Scientists believed that about 10% of the earth's land area is covered by loess.<span />
