300 Part IV: Putting It All Together: Practice Tests Passage 3 Lightning has been a mystery since early times. People of ancient civilizations be- lieved angry gods threw lightning bolts from the sky. Nobody understood that lightning resulted from electricity until Ben Franklin flew a kite with a key dangling from the string, and it was struck by lightning. In current times, it is known that lightning has a very scientific cause. Generally, within a storm cloud, friction from water and ice- laden clouds creates a negative charge at the bottom of the cloud. When that charge grows too great for the air to hold it back, it is united with a positive charge from the Earth, creating a channel of electricity that flows between the two points. The charge remains invisible as it moves towards the ground un- til it meets the charge rising from the ground. Once they meet, a fifty thousand degree cur- rent superheats the air around the channel, resulting in an explosion of sound known as thunder. In fact, very recently it has been dis- covered that occasionally the positive charges appear at the bottom of the cloud, which are then met by negative charges from earth. Florida leads the nation in lightning deaths. Approximately ten people die each year in Florida from lightning, which surpasses the number of deaths caused by the winds of other weather events such as tornados and hurricanes. Lightning is much harder to fore- cast than a storm. Forecasters can indicate when a storm is likely to produce lightning, but there is no way to know when or where lightning will actually strike. It is known that it can actually strike up to 25 miles from the center of a storm, which occurs when light- ning originates under a cloud but travels hor- izontally for a time before turning towards earth. Thunder is only heard up to ten miles from where lightning strikes, so it is possible to be struck by lightning without even realiz- ing there is a storm in the area. Generally, people are injured by lightning when they are in the open, near or in water, or near tall structures like trees. Golfers, swimmers, beach-goers, and outdoor work- ers are in greatest danger. The greatest num- ber of victims are males, but it is believed that this is because males are more likely to be in the places where lightning strikes. When lightning is about to strike, one feels an odd, tingling sensation, and one’s hair stands on end. Of course, there is little chance to do anything about it, because the full blow will occur within a second and be over in a couple of seconds. The victim may be thrown, lose consciousness, be burned, die, or suffer permanent injury. Some people recover completely, but others do not. 31.

The trees are referred to as stranglers be- cause of the way they envelope other trees. Yet, the expression strangler is not quite ac- curate because the fig trees do not actually squeeze the trees on which they piggyback nor do they actually take any nutrients from the host tree. But they may stifle the host tree’s growth as the fig tree’s roots meet and fuse together, forming rigid rings around the host’s trunk and restricting further growth of the supporting tree. The most interesting aspect of the strangler fig is that it grows from the sky down to the ground. Birds are a major factor in the birth of new fig trees, ingesting the fruit and later dropping the seeds contained in them. Most seeds that are dropped to the ground do noth- ing, but those that drop into a moist mulch of decayed leaves and mosses that have col- lected in branches of trees have a chance of survival. They are more likely to receive some sunlight than those that drop all the way to the ground. After the seeds of the fig trees germinate high in the canopy, their roots descend to form a menacing vise around the trees that support them. Eventually the host tree may begin to die, but it may take many years. Some types of fig trees put down roots so thick that they completely surround the host. In that case, all that is left is a moss-covered scaf fold of fig roots. 38. According to the passage, fig trees are referred to as stranglers because they A. are unknown. B. are unusual. C. wrap themselves around other trees. D. kill wildlife. 39. The author implies that the term strangler is not accurate because A. while the fig trees may damage the host tree, they do not actually squeeze it. B. the host tree actually strangles the fig. C. the fig tree does not harm animals. D. the fig tree provides nutrition to the host tree. 40. The word stifle in the second paragraph is closest in meaning to A. assist. B. nourish. C. suffocate. D. live on. 41. The author indicates that the fig trees A. grow from seeds dropped to the ground. B. grow from the top of a tree down to the ground. C. grow from the ground up. D. receive nutrients from the host tree. For more material and information, please visit Tai Lieu Du Hoc at www.tailieuduhoc.org 303 Practice Test 5 Section 4 Writing 42. The word fuse in the second paragraph is closest in meaning to A. combine. B. avoid. C. cannibalize. D. enjoy. 43. The word mulch in the third paragraph is closest in meaning to A. rock. B. compost. C. seeds. D. moss. 44. The word menacing in the final paragraph is closest in meaning to A. friendly. B. strong. C. spiraling. D. ominous. 45.
