Grim disappeared upstairs himself, and returned about ten minutes later in the uniform of a Shereefian officer--that is to say, of Emir Feisul's Syrian army. Nothing could be smarter, not anything better calculated to disguise a man. Disguise, as any actor or detective can tell you, is not so much a matter of make- up as suggestion. It is little mannerisms--unstudied habits that identify. The suggestion that you are some one else is the thing to strive for, not the concealment of who you really are. Grim's skin had been sun-tanned in the Arab campaign under Lawrence against the Turks. The Shereefian helmet is a compromise between the East and West, having a strip of cloth hanging down behind it as far as the shoulders and covering the ears on either side, to take the place of the Arab head-dress. The khaki uniform had just enough of Oriental touch about it to distinguish it from that of a British officer. No man inexperienced in disguise would dream of choosing it; for the simple reason that it would not seem to him disguise enough. Yet Grim now looked so exactly like somebody else that it was hard to believe he was the same man who had been in the room ten minutes before. His mimicry of the Syrian military walk--blended of pride and desire not to seem proud--was perfect.

Tocqueville asserted that the values that had triumphed in the North and were present in the South had begun to suffocate old-world ethics and social arrangements. Legislatures abolished primogeniture and entails, resulting in more widely distributed land holdings. This was a contrast to the general aristocratic pattern in which only the eldest child, usually a man, inherited the estate, which had the effect of keeping large estates intact from generation to generation. In America, in contrast, landed elites were less likely to pass on fortunes to a single child by the action of primogeniture, which meant that as time went by, large estates became broken up within a few generations which, in turn, made the children more equal overall. It was not always a negative development, according to Joshua Kaplan's interpretation of Tocqueville, since bonds of affection and shared experience between children often replaced the more formal relation between the eldest child and the siblings, characteristic of the previous aristocratic pattern. Overall, in the new democracies, hereditary fortunes became exceedingly difficult to secure and more people were forced to struggle for their own living. This rapidly democratizing society, as Tocqueville understood it, had a population devoted to "middling" values which wanted to amass, through hard work, vast fortunes. In Tocqueville's mind, this explained why America was so different from Europe. In Europe, he claimed, nobody cared about making money. The lower classes had no hope of gaining more than minimal wealth, while the upper classes found it crass, vulgar, and unbecoming of their sort to care about something as unseemly as money; many were virtually guaranteed wealth and took it for granted. At the same time in America, workers would see people fashioned in exquisite attire and merely proclaim that through hard work they too would soon possess the fortune necessary to enjoy such luxuries. Despite maintaining with Aristotle, Montesquieu, and others that the balance of property determined the balance of power, Tocqueville argued that, as America showed, equitable property holdings did not ensure the rule of the best men. In fact, it did quite the opposite. The widespread, relatively equitable property ownership which distinguished America and determined its mores and values also explained why the American masses held elites in such contempt.

Question: "How did Europeans' and Americans' attitudes toward amassing wealth differ?"

Answer: "Europeans left their wealth to the eldest, americans split it up"

Response: yes

Density is also an important physical property of matter. The concept of density combines what we know about an objects mass and volume. Density reflects how closely packed the particles of matter are. When particles are packed together more tightly, matter is more dense. Differences in density of matter explain many phenomena. It explains why helium balloons rise. It explains why currents such as the Gulf Stream flow through the oceans. It explains why some things float in or sink. You can see this in action by pouring vegetable oil into water. You can see a colorful demonstration in this video.

Question: "How can I understand density?"

Answer: "By listening to friends"

Response: no

Breathing is the process of moving air into and out of the lungs. The process depends on a muscle called the diaphragm. This is a large, sheet-like muscle below the lungs. Inhaling, or breathing in, occurs when the diaphragm muscle tightens. This increases the size of the chest. This too decreases air pressure inside the lungs. This action allows air and gases to enter the lungs. Exhaling, or breathing out, occurs when the diaphragm muscle relaxes. This decreases the size of the chest. This increases air pressure inside the lungs. This action allows for air to leave the lungs. When you inhale, air enters the respiratory system through your nose and ends up in your lungs, where gas exchange with the blood takes place. What happens to the air along the way? In the nose, mucus and hairs trap any dust or other particles in the air. The air is also warmed and moistened. Next, air passes through a passageway that is connected to the windpipe. The air then finds its way to the lungs. In the chest, the windpipe splits so that air enters both the right and left lung.

Question: "When you exhale, why does air leave your lungs?"

Answer: "To enter respiratory system"

Response:
no
