I'm taking a test and have to guess the right answer to the question after the article. Article: Tuvalu, a tiny country in the Pacific Ocean, has asked for help as it fears it will be swallowed up by the sea. Storms and huge waves are a constant threat and none of Tuvalu's nine little islands is more than five metres above sea level. Salt water is already entering the country's drinking water supply, as well as damaging plants that produce fruit and vegetable. Without urgent help, the country's days are numbered. But Tuvalu is not the first place to face sinking into the sea. Venice, a historic city in Italy best known for its canals, has sunk about 24 cm over the past 100 years. Experts say that it will have sunk another 24 cm by 2050. A century ago, St. Mark's Square, the lowest point in the city, flooded about nine times a year. Nowadays, it happens more than 100 times. While Venice is slowly sinking into the mud on which it stands, Tuvalu's rising sea level is caused by global warming. The average global temperature has increased by almost 0. 5 centigrade degrees over the past century, scientists expect it to rise by extra 1.3 degrees over the next 100 years. Warmer weather makes glaciers melt, adding more water to the ocean. The warmer temperatures also make water expand, so it takes up more space, causing the sea level to rise. The sea level has risen 10.25 cm in the last 100 years. The main cause of global warming is human pollution. Through burning coal, oil and gas, people have been increasing the greenhouse gases in the atmosphere, such as CO2. This adds to the power of the greenhouse effect, making the planet even warmer. Many scientists believe that, if the warming is not stopped, there will be huge climate changes. The sea level could rise by one meter this century. Should this come true, the sea will swallow up millions of homes and the world will be flooded with " _ " looking for somewhere to live. Question: Which of the following is NOT true according to the passage? Options: A: Tuvalu's nine little islands are less than five meters above the sea level. B: The average global temperature has risen by 13 centigrade degrees over the past 100 years. C: The warmer temperature causes the sea level to rise. D: There will be huge climate changes unless the warming is stopped.

I'm taking a test and have to guess the right answer to the question after the article. Article: It's hard to track the blue whale, which has almost been killed off by commercial whaling. Attaching radio devices to it is difficult and visual sightings are too unreliable to give real insight into its behavior. So biologists were delighted early this year when, with the help of the US Navy, they are able to track a particular blue whale for 43 days recording its sounds. This was possible because of the Navy's former top secret system of underwater listening devices across the oceans. Tracking whales is but one example of an exciting new world just opening to civilian scientists after the cold war as the Navy starts to share and partly uncover its global network of underwater listening system built over the decades to track the ships of potential enemies. Earth scientists announced at a news conference recently that they had used the system for closely observing a deep-sea volcanic eruption for the first time and that they planned similar studies. Other scientists have proposed to use the network for tracking ocean currents and measuring changes in the ocean and global temperatures. Different layers of ocean water can act as channels for sounds focusing them in the same way a stethoscope does when it carries faint noises from a patient's chest to a doctor's ear. This focusing is the main reason that even relatively weak sounds in the ocean, especially low-frequency ones, can often travel thousands of miles. Question: The deep-sea listening system makes use of _ . Options: A: the ability of sound to travel at high speed B: the top-level technology of focusing sounds under water C: the unique characteristic of layers of ocean water in carrying sound D: low-frequency sounds traveling across different layers of water

I'm taking a test and have to guess the right answer to the question after the article. Article: One Tuesday evening in the beginning of the fall 1996 semester at Shippensburg University, sirens sounded. These sirens were not in celebration; they were a cry to the university that something was wrong. A house, only one block away, was on fire. Nine of the university's students lived there. From the minute the word got out that help was needed, it seemed like everyone showed up. The victims of the fire were offered endless invitations for housing for the night. The very next day, everyone to do their part in helping them. Flyers were posted with items that were immediately needed, just to get these students through this next couple of days. Boxes for donations and money jars were placed in every residence hall . As a residence director,I went before the students in my hall to ask them to do what they could. I knew that college students don't have much, but I asked them to do their best: "Every little bit will help." I really didn't think they could do much. I was proved wrong. At the hall council meeting the night after the fire, my residents decided to have a wing competition, where each wing of the building would team up to see who could bring In the most donations. I announced that the wing who won would receive a free pizza party. Thursday evening we announced over the PA system that we were beginning the wing competition. Within minutes, the place exploded. The single large box that I had placed in the lobby was over-flowing. We quickly grabbed more boxes, and we watched in amazement as they, too, filled to the brim. Members of the resident assistant staff and I began to count the items. I was astonished by what I saw, and I was inspired by these kids. When we came to the final tally , the winners turned to me and announced that they would like to donate their winnings as well. They wanted the victims of the fire to have their pizza party. Tears welled up in my eyes. I had watched these students jump to action, work tirelessly and donate all that they could. And then, as if that were not enough,... Question: How did the residence director feel when he saw the brimful boxes? Options: A: Terrible. B: Funny. C: Surprised. D: Serious
