Read the passage through once before answering the questions. For some questions, you should read beyond the indicated portion before you answer.PassageA Flute in the ForestA quiet walk along a forest path during an early spring dusk (1) surprisingly revealed an unexpected gift of nature. The sound of a flute seemed to float from the tallest trees in the near distance. This flute song was like none ever made by man. Our guide quickly raised his hand in a signal for us to stop and remain still, and then whispered these simple words: “Wood Thrush.” (2) Truly, any attempts to describe this spectacular birdsong with words does a grave injustice to its unique vocalizations.The Wood Thrush is a rather plain, brown, robin-like bird. Its most distinctive features are its white spotted chest and pinkish legs. Viewing these birds can be especially (3) difficult, as they enjoy perching on the tallest branch that is still able to offer seclusion among its leaves and twigs. Binoculars are a must. With each Wood Thrush song, a birdwatcher is able to track the bird’s location. Because it is a migratory bird, early spring is generally the first opportunity to observe the Wood Thrush in the United States. (4) A mixed forest is its preferred habitat, one with both deciduous and evergreen trees of varying heights. Interestingly, while the Wood Thrush enjoys singing from the tallest branches, (5) it’s nest is often found much closer to the ground.1. (6) As the birds settle into their spring nesting areas, the race to find a mate starts in earnest.2.Fortunately for bird lovers, this is when the male Wood Thrush begins perfecting his song as he attempts to attract a willing female.3. Starting in the late evening, just as dusk begins to encompass the landscape and most other birds have quieted down, the Wood Thrush tentatively begins his symphony of love.4. (7) His songs come in distinct parts, and he can sometimes even sing two sweet notes simultaneously.5. His concert generally lasts for a full half hour, and he completes more than 100 songs in that time.6. With each song, the listener (8) begins to hear this fancy flutist working on new combinations of notes, extending a particular collection of chords, and changing pitch and volume at will.7. Abruptly, the singing stops, (9) indicating that the bird’s pure exhaustion. (10)(11) Following a long rest, the male Wood Thrush awakens to begin his quest a new. Early in the morning, before the other forest birds awaken, the Wood Thrush (12) by starting his melody all over again, waking the world up to another long and (13) harmonious musical arrangement. It seems unimaginable that more than one such display is necessary to attract an interested partner, but the songs continue for the entire spring and even into the summer months. One can only determine that the Wood (14) Thrush chosen female and subsequent offspring are begging him (15) for to keep singing. As poet Henry David Thoreau wrote, the Wood Thrush “alone declares the immortal wealth and vigor that is in this forest.”Q. (7)

On a recent tripto Quebec City, (1) nevertheless, my concept of how fast humans can move was radically altered. It was Carnaval season, the time when people from across the province and the world (2) flocking to the old walled city for two weeks of food, drink, revelry, and winter sports. Normally, I go to Carnaval looking for the rare thrill, all the better if it requires a helmet and my signature on a release of liability. (3) This time for me, it was full-contact downhill ice-skating. (4)The course looked a lot like a bobsled run. From the top of the mountain a sturdy metal chute descended that wound left and right on its way down. About eight inches of icepack covered the metal surface, which was wetted twice daily to maintain an ideal slickness. If by the time you reach the end of the chute you still haven’t regained your (5) footing, there’s a line of meter-thick foam padding to absorb your crash.The thrill seeker in me was chomping at the bit to try out this new sport. I signed up and put on my helmet. The organizer quickly looked me over (6) shooting me a sarcastic grin. (7) Smiling back and giving him a brief nod, I mounted the chair lift for the top of the mountain and prepared to watch the few heats that came before mine.The first heat of the day (8) went smooth and gave me a good idea of what was permitted and what was against the rules, as well as good and bad technique on the chute. (9) Professionals were what the first five racers looked like. They calmly and silently approached the starting line, which was at the head of a 20-meter flat strip of ice that racers use to gain speed before entering the downhill section. The starting gun rang out and a few men began with powerful strides, landing them at the head of the pack. When they all entered the chute, their striding stopped and the physical contact began. (10) This is the time I learned that full hockey-style body checks are perfectly legal, as one competitor veered sharply to his left, knocking the smallest racer up and over the wall of the chute and into the meters-deep powdery snow that lined the outside of the chute. (11) Racing continued with countless rounds of hip checks and slippery maneuvers. By the end of the race, only three men were on their feet—it was a photo (12) finish. As the large digital-display on both ends of the run showed that the men had approached speeds of sixty miles per hour.Luckily, they seeded me in a heat with four other first-timers. When the starting gun sounded, I was quickly off to the (13) pack’s head. I shot down the track surprisingly smoothly when I suddenly realized I had no competition.I looked back and saw the other four skaters splayed out on the ice sliding helplessly toward the finish line.

Directions: Read the passage and choose the best answer to each question.PassageResearchers have noticed sudden decay in limestone grave markers in a cemetery downwind from a coal-burning power plant. Two studies were conducted to examine this decay process.Study 1A key mineral component of limestone is feldspar, which is also abundant in ground soil. Feldspar, as it weathers and decays, breaks down into another mineral, kaolinite. The weathering process is often expedited by moisture from rain and humidity. Researchers measured the levels of feldspar and kaolinite in the soil of the cemetery and otherlocations at speciﬁc distances from the cemetery before and after rain showers. The results are shown in Table 1. (Note: The soil sample sizes were the same for each location tested.)Study 2The researchers believe that the emissions from the nearby power plant are somehow affecting the decay of the limestone. Levels of common gases – carbon dioxide (CO2), oxygen (O2), nitrogen dioxide (NO2), and sulfur (S) – in the atmosphere were tested at the cemetery and other locations at speciﬁc distances from both the cemetery and the power plant. Measurements in parts per million (ppm) were recorded in Table 2.Q.Carbon monoxide is another gaseous byproduct associated with coal-burning power plants. If carbon monoxide levels behave like the sulfur gas levels in Study 2, one would expect that carbon monoxide levels
