They live off geothermal energy instead of sunlight. There are two species of the tube worm family, with very different lengths of life and growth rates, but similari- ties as well. The slow-growing tube worms are known to live as long as 250 years, making them the longest-living sea invertebrates known. This species lives near cold sea-floor seeps and may not grow at all from one year to the next. Even when they do grow, it is generally from a half an inch to four inches per year. In spite of their slow growth, due to their long lives, they can reach nine feet before they die, although they are thinner than the hot-water worms. The seeps under the slow-growing tube worms are rich with oily materials. The envi- ronment in which they live is slow and peaceful, stable and low-energy. The cold- water seeps and the tube worms that reside there may live hundreds or thousands of years. In stark contrast, the fast-growing tube worms live a quick and short life, growing rapidly. They attach themselves near hot steaming vents that force water into the sea, growing about two and a half feet a year, and up to eight feet overall . They live by absorb- ing sulfur compounds metabolized by bacte- ria in a symbiotic relationship. The hot water vents spew forth scalding wa- ter filled with hydrogen sulfide, which the tiny bacteria living in the worms’ tissues consume. These tube worms live a rapid life, with none of the relaxing characteristics of the cold-water tube worms. 1. The word anchored in the first sentence is closest in meaning to A. affixed. B. contentedly. C. feeding. D. above. 2. The expression spew forth in the first sentence is closest in meaning to A. inhale. B. discharge. C. control. D. eliminate.

Aneurysms are blood sacs formed by en- largement of the weakened wall of arteries or veins. They are dangerous and thus must generally be removed before they cause con - siderable damage. If one ruptures, it can cause strokes or fatal hemorrhaging, the lat- ter of which occurs in 50 percent of all pa- tients. Before rupturing, an aneurysm frequently shows no sign or symptom that it exists. Brain aneurysms occur in approxi- mately 5 percent of the population. Most pa- tients are between 40 and 65 years old, with hemorrhages most prevalent in those be- tween 50 and 54. The new procedure involves inserting a soft, flexible micro-catheter through the femoral artery in the groin area and snaking it up through blood vessels to the brain. Inside the catheter is a small, coiled wire, which can be extruded after it reaches its destination. After the coil is outside the catheter, a low voltage electrical current is applied, and the coil de- taches at a preset solder point. Additional coils are snaked through the catheter and also detached at the site, creating a basket, or metal framework, which causes the blood to clot around it. The micro-catheter is with - drawn, the clot remains, and the healed aneurysm no longer is exposed to the stress that can cause another rupture. The procedure lasts two hours, which is half as long as invasive surgery, and recovery time is generally limited to a few days in- stead of a few weeks. The procedure was discovered in the 1990s, was approved by the U.S. Food and Drug Administration in 1995, and is available in various hospitals where there are advanced neurology depart- ments and specialists trained in the proce- dure. Many lives have been saved by use of the procedure, because the alternative would have been to watch and wait rather than risk the hazards of surgery. 10 . The author implies that the procedure described is useful for A. all aneurysms. B. aneurysms that occur anywhere in the brain. C. aneurysms that occur near the brain stem only. D. aneurysms that occur near large blood vessels. 11. The word They in the first paragraph refers to A. aneurysms. B. brain stems. C. surgeries. D. procedures. 12 . The word considerable in the first paragraph is closest in meaning to A. slight. B. kind. C. significant. D. recurring. 13 . The word one in the first paragraph refers to A. brain stem. B. aneurysm. C. procedure. D. surgery. For more material and information, please visit Tai Lieu Du Hoc at www.tailieuduhoc.org 14 . The word snaking in the second paragraph is closest in meaning to A. meandering. B. extruding. C. living. D. damaging. 15 . The word withdrawn in the second paragraph is closest in meaning to A. removed. B. too large. C. charged. D. inserted. 16 . An aneurysm is most similar to A. an ulcer. B. a hernia. C. a heart attack. D. cancer. 17. The author indicates that half of the patients who have a brain aneurysm could also have A. a stroke. B. a seizure. C. a heart attack. D. hemorrhaging that results in death. 18 . The author indicates that the point of creating a basket near the aneurysm is to A. catch the aneurysm when it breaks off. B. serve as a base for a blood clot to form. C. dissolve the aneurysm. D. provide a means of studying the aneurysm. 19 . The author indicates that the femoral artery is A. small. B. in the upper thigh. C. in the brain. D. connected to the brain. 20. The author states that the electrical charge is applied in order to A. stimulate the brain. B. stimulate the aneurysm.

C. at a predetermined and prepared location on the wire. D. inside the micro-catheter. 22. According to the passage, traditional surgical techniques take A. longer and require more recuperation time than the new procedure. B. longer but require less recuperation time than the new procedure. C. less time and require less recuperation time than the new procedure. D. less time but require longer recuperation time than the new procedure. 279 Practice Test 4 Section 3 Reading GO ON TO THE NEXT PAGE For more material and information, please visit Tai Lieu Du Hoc at www.tailieuduhoc.org . www.tailieuduhoc.org 278 Part IV: Putting It All Together: Practice Tests Passage 2 A new procedure has been developed to treat aneurysms, particularly those. material and information, please visit Tai Lieu Du Hoc at www.tailieuduhoc.org 30.
