Question:

A store keeps exactly 173 apples stocked in the produce section. A man buys 27, then comes back and returns 12. How many apples does the store need to replace in the display?

Lenora W.
Answer:

The display starts with 173 apples, loses 27, then gains 12 again. In order to figure out how many apples are still gone, there are several equations that can solve this. The easiest is to recognize that the display started with exactly 173 apples, and only lost the 27. The man adds 12 back, so whatever 27 - 12 is, that's how many apples are still missing. 27 - 12 = 15, so in order to have a full display of apples again, the store needs to restock 15 apples.

Question:

Guilio Briccialdi, a flute virtuoso from the 19th century, helped to contribute what mechanical developments to the flute?

Lenora W.
Answer:

Guilio Briccialdi lived during a time that it was very difficult to play the flute. The awkward forked fingerings made it very difficult to play technical passages, or to even learn the fingerings to begin with. During this time, there were a lot of different people making a lot of different mechanical developments to the instrument in an attempt to make it far more playable. Briccialdi's most famous development was the development of the lever Bb key, sometimes known as the Briccialdi key. This development allowed the player to not have to use forked fingerings on a few more notes than previously possible, and the key is still used today.

Question:

What were some of the factors leading up to the French Revolution (1789)?

Lenora W.
Answer:

There were many factors that led up to it, and historians tend to disagree on many smaller factors. A few factors that the vast majority of historians agree upon, however, are such that Louis XVI was a poor absolute ruler. He had tried to continue on his grandfather's reign (Louis XIV) of an absolute monarch, but Louis XVI himself was too weak. This made the French citizens unhappy, of course, and made them demand a better form of government. What better time to demand for enlightenment than when the first country was born from the ideals of the Enlightenment? The French had helped the United States win the revolutionary war, and since then they've seen more and more Enlightenment ideology be implemented successfully into a functioning, modern government. They wanted that too, so the citizens took matters into their own hands, and thus the French Revolution began.
