Answer:
Silk is hard to produce and rich in price.
Explanation:
Silk is a particular item as it cannot be produced everywhere. Silk comes from the silkworm and is a rich material known for its sooth, yet warm feeling. These worms are very particular about where they can be inhabited and in many cases will die if not in the right enviornment. Additionally, silk is seasonal. Just like butterflies, birds, and flowers, during the times of cold, silkworms do not produce silk. Therefore the substance is quite hard to obtain, but rich in price.

Answer:
250 pine trees
Explanation:
If we have a one square mile of forest that is divided into ten equally sized quadrants, that means that each of them accounts for 1/10th of a mile. If in one of the quadrants there are twenty-five pine trees, and if that is the number of pine trees in all of the quadrants, then we can easily come to the result for the whole forest. As each quadrant is 1/10 of the whole area, it means that the number of pine trees in one of them should be multiplied by the number of quadrants:
25 x 10 = 250
We get a result of 250 pine trees for the whole forest area of one square mile.
