Answer:

Birds’ feathers are designed to be light but very strong, flexible but very tough. Although it looks like feathers grow all over a bird, they actually grow in specific areas called feather tracks. In between the feather tracks are down feathers. This keeps the body weight down.

Feathers are made of a tough and flexible material called keratin. The spine down the middle, called the shaft, is hollow. The vanes are on the two halves of the feather. They are made of thousands of branches called barbs. Because there are many spaces between these barbs, a feather has as much air as matter.

What pull factor is a main reason for Mexican immigration to the United States? A) better jobs B) higher wages C) medical care D
Delicious77 [7]

Even though all of the above reasons may be critical pull factors, we could safely lean towards option B, <em>higher wages</em>, as the most indicative answer. Mexicans did not necessarily get better jobs than they had back in their native country, where they may even have been skilled and educated professionals; in fact, wages may have been significantly higher in comparison to their earnings at home, allowing them for having a better quality of life and affording medical care, which tends to be expensive in the USA. Education is not necessarily free -especially at its highest levels, which would help migrants and their offspring to still further improve their quality of life- but then again, higher wages could open the possibility of accessing some private higher education.

D. The sum of borrowed and return is a positive even number.

At a point where the number of borrowed laptop and return laptop is zero, it is an indication that a particular laptop is not currently borrowed. For instance, if in a particular period of time a total number of borrowed computer is 50 and the total number of returned is 50 (50 - 50 = 0) it implies that no laptop is unreturned. While on the other hand if the number of borrowed and returned is a positive even number, this also implies that the number must be one of (even number) i.e 2,4,6,8,10,12,14,16,18,20 etc.
