People dive fast. Many accidents happen.

The faster people dive, the more the number of accidents that will happen.

Explanation: Quick ascents can lead to decompression illness. During a dive, a diver’s body absorbs nitrogen gas. The nitrogen gas compresses due to water pressure following Boyle’s Law, and slowly saturates his body tissues. If a diver ascends too quickly, the nitrogen gas in his body will expand at such a rate that he is unable to eliminate it efficiently, and the nitrogen will form small bubbles in his tissues. This is known as decompression sickness, and can be very painful, lead to tissue death, and even be life threatening. In a worst-case scenario, a diver who ascends quite rapidly may rupture small structures in his lungs known as alveoli. In this case, bubbles may enter his arterial circulation and travel through his body, eventually lodging in blood vessels and blocking blood flow. This sort of decompression illness is called an arterial gas embolism (AGE), and is very dangerous. A bubble may lodge in an artery feeding the spinal column, in the brain, or in a host of other areas, causing loss or impediment of function. Maintaining a slow ascent rate greatly reduces the risk of all forms of decompression illness.

explanation:

the silver bells of the sleds are merry and keep time in the winter nights while the sky twinkles happily. the golden bells of weddings are delightful in their peaceful happiness, foretelling a rapturous future. meanwhile, the brazen alarm bells scream frightfully in the night, with a discordant and desperate sound. in their clamor, these bells convey terror, horror, and anger. finally, the iron bells are solemn and melancholy, while those in the church steeple are like ghouls who feel happiness. the king of the ghouls, who rings the bells, cheerfully keeps time with the moaning and groaning bells.

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
