  • Q #1: Letter from the chair of Elkinsiville Society Many of you have heard about the proposed northward expansion of the Interstate, which currently ends just south of Elkinsiville. In the recent debate over how it this work go forward, the focus has been on weighing economic costs and benefits. Indeed, many local politicians claim to favor the project because it will bring jobs in the short term and more visitors to Elkinsiville in the long term. These politicians also argue that the proposed plan is the least environmentally damaging way to expand the highway farther upstate. This cannot be true, however, since the proposed expansion involves not just the widening of existing roads, but also the construction of more than a dozen miles of new-terrain highway.   Which of the following statement can be supported by evidence from the passage?

    A. There are no Elkinsiville Environmental Society members among the city’s politicians

    B. A detailed environmental study of the northern expansion of the interstate has been conducted by Elkinsiville Ecological Society

    C. The Elkinsiville Ecological Society will continue to oppose the northern expansion of the interstate

    D. Politicians in Elkinsiville will win their efforts to approve the northern expansion of the interstate highway.

    Answer Explanation

    This can be supported by the statement,” This cannot be true, however, since the proposed expansion involves not just the widening of existing roads, but also the construction of more than a dozen miles of new-terrain highway.”

  • Q #2: A day with Humpbacks I sat on the deadlands of Neah Bay, Washington, and watched a mother humpback and her calf slip through the icy Pacific waters. I recognized this humpback by her distinctive tall patterns, as unique to her as my fingerprints are to me. Once, heavy hunting using harpoons decimated populations of humpbacks, but they have since started to recover. As this gray female rises to the surface, she exhales, sending up a spout nearly 20 feet high. She rolls on her side and lifts her scalloped edge flipper in salute, then slaps it on the water. I adjust my lens and take a shot. This is the only type of whale hunting I find acceptable – hunting with a camera! Which of the following statements conveys the main idea of the passage?

    A. This particular humpback whale has never been seen previously by the author

    B. Humpback whales travel in waters near Washington

    C. Cameras and harpoons are both ways of hunting humpbacks

    D. Humpbacks while populations are finally recovering after nearly being wiped out.

    Answer Explanation

    Choice D conveys the main idea of the passage because it talks about the recovery of humpback whale populations after they were nearly wiped out due to heavy hunting using harpoons.

    The passage describes the author's experience watching a mother humpback and her calf, and while there are other details mentioned, the main focus is on the recovery of humpback whales after sustained hunting. The other choices are not the main focus of the passage and are either incorrect or not directly related to the main idea.

  • Q #3: What is all this talk of cicadas lately in the United States? You might be wondering why the media has featured it, but in fact, the discussion about cicadas has emerged about as predictably as the cicadas themselves from their underground refuge. Let's get oriented with some background on cicadas. What is a cicada? A typical definition will at least tell you that the cicada is large, loud insect with long transparent wings and it is mostly found in warm countries. A more detailed response might also inform you that cicadas have short antennae and wide-set eyes that jut out. With delicate, translucent wings — and that not only are the cicadas loud, but few creatures make a louder sound. In fact, it is the male cicadas that are the noisy ones to the tune of 80 to 100 decibels, with sound like the roar of a loud engine. This is because male cicadas make a strident, high buzzing sound by vibrating two membranes on the abdomen called tymbals, effectively turning its body into a kind of echo chamber or drum. Female cicadas cannot replicate the buzzing, though they respond with a clicking sound when they are ready to mate. Although there are several species of cicada, mating typically takes place in trees wherever the female deposits the eggs into the bank. When the eggs hatch, the larval cicadas, called nymphs, drop to the ground and burrow. They then live as nymphs for most of their lives over 6 feet underground with both male and female cicadas dying within weeks of their emergence from the soil. This is particularly true for North American cicadas especially the mogucicada.   Which of the following events happens first after the male cicada calls to the female cicada, according to the passage?

    A. The male and female mate in the trees

    B. The female deposits the eggs

    C. Nymphs drop to the ground

    D. The female makes a clicking sound

    Answer Explanation

    When the male cicada calls out to the female cicada with the loud buzzing sound, the female would then respond with her own sounds.

    According to the passage, female cicadas cannot replicate the buzzing, though they respond with a clicking sound when they are ready to mate. This is the next thing that happens after the male cicada calls out.
