The population grew rapidly, from 800,000 in 1814 to 914,000 in 1830 and 1,067,000 in 1846. The combination of economic and demographic factors led to hunger, housing shortages and a lack of work for young people. Thus, it is not surprising that people left Alsace, not only for Paris where the Alsatian community grew in numbers, with famous members such as Baron Haussmann but also for more distant places like Russia and the Austrian Empire, to take advantage of the new opportunities offered there: Austria had conquered lands in Eastern Europe from the Ottoman Empire and offered generous terms to colonists as a way of consolidating its hold on the new territories. Many Alsatians also began to sail to the United States, settling in many areas from 1820 to 1850. In 1843 and 1844, sailing ships bringing immigrant families from Alsace arrived at the port of New York. Some settled in Illinois, many to farm or to seek success in commercial ventures: for example, the sailing ships Sully (in May 1843) and Iowa (in June 1844) brought families who set up homes in northern Illinois and northern Indiana. Some Alsatian immigrants were noted for their roles in 19th-century American economic development. Others ventured to Canada to settle in southwestern Ontario, notably Waterloo County.

Ah, so.. unanswerable

The essence of air defence is to detect hostile aircraft and destroy them. The critical issue is to hit a target moving in three-dimensional space; an attack must not only match these three coordinates, but must do so at the time the target is at that position. This means that projectiles either have to be guided to hit the target, or aimed at the predicted position of the target at the time the projectile reaches it, taking into account speed and direction of both the target and the projectile.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Projectiles must either be guided to the target or aimed where?
Ah, so.. at the predicted position of the target at the time the projectile reaches it

Clothing protects against many things that might injure the uncovered human body. Clothes protect people from the elements, including rain, snow, wind, and other weather, as well as from the sun. However, clothing that is too sheer, thin, small, tight, etc., offers less protection. Clothes also reduce risk during activities such as work or sport. Some clothing protects from specific environmental hazards, such as insects, noxious chemicals, weather, weapons, and contact with abrasive substances. Conversely, clothing may protect the environment from the clothing wearer, as with doctors wearing medical scrubs.

Ah, so..
