PASSAGE 2: Read this passage to answer questions 13-17. Sunscreen [A] From broad-brimmed hats to UV-blocking sunglasses, people are always looking for ways to protect themselves from too much sun. A little bit of sun exposure is necessary for our health, but too much can lead to deadly cancer. So how much is too much? A new product on the market, L’Oreal’s UV Sense, has been designed to help answer this question. [B] L’Oreal’s UV Sense is a skin sensor that detects UV rays. It is considered preventative “skintech” – a device worn on the skin to help prevent health risks, such as skin cancer. It does not block the sun physically, like sunscreen does, but it helps its wearer know how much UV light he or she is exposed to. [C] The sensor is housed in a small sticker that can fit on a person’s thumbnail. Style-conscious wearers can choose from over 50 sticker designs. They place the sticker on a pair of favorite sunglasses, a watch, or anywhere else that will receive direct sunlight. As the wearer walks to the mail box, lies out on the beach, or sits in rush-hour traffic, the device collects data on how much sun the wearer is being exposed to. The device delivers this data to the wearer’s smartphone, and alerts him or her when the level of UV rays is dangerously high. This information prompts the wearer to seek shade or apply more sunscreen. [D] This product differs from other wearable devices in that it is meant to be used for a short period of time until wearers learn which situations cause them to get the most UV rays. Wearers use the sticker for about two weeks and then disposes of it. The expectation is that wearers will become more aware of their sun exposure and change their habits or lifestyle accordingly. This means consumers can benefit from an inexpensive product, since longer-lasting ones cost hundreds to thousands of dollars. [E] So why would a cosmetic company like L’Oreal invest in technology that consumers will only use once or twice? The cosmetic giant understands that wearable devices are the latest trend on the market. They also understand how concerned consumers are about the rise of skin cancer. In response to their market research, L’Oreal wants to take the lead before other skincare companies develop similar products. The quest for developing preventative skintech has just begun and will most likely never end. QUESTION:  What does cosmetic giant in paragraph E refer to?

“If you want something done, give it to a busy person.” That advice sounds strange at first, but people with energy and ambition often get results. Time and again, people with ambition accomplish things that others thought were impossible. Whether a person wants to set a world record, or rise to the top of a company, ambition is one of the qualities that is most needed. Which of these choices best sums up what the paragraph is about in one sentence?

DIRECTIONS: Read each sentence. Decide if the use of the underlined word in each sentence makes the statement T (true) or F (false). [1] If you enhance something, you make it better.

PASSAGE 1: Read this passage to answer questions 2-6. Sacred Summits [A] Volcanoes are creators and destroyers. They can shape lands and cultures, but can also cause great destruction and loss of life. Two of the best-known examples are found at opposite ends of the world, on the Pacific Ring of Fire. Symbol of Japan [B] It’s almost sunrise near the summit of Japan’s Mount Fuji. Exhausted climbers, many of whom have hiked the 3,776 meters through the night to reach this point, stop to watch as the sun begins spreading its golden rays across the mountain. For the climbers, this is an important moment. They have witnessed the dawn on Mount Fuji – the highest point in Japan. [C] Mount Fuji is a sacred site. Japan’s native religion, Shintoism, considers Fuji a holy place. Other people believe the mountain and its waters have the power to make a sick person well. For many, climbing Fuji is also a rite of passage. Some do it as part of a religious journey; for others, it is a test of strength. Whatever their reason, reaching the top in order to stand on Fuji’s summit at sunrise is a must for many Japanese. Every July and August, hundreds of thousands attempt to do so. [D] Fuji is more than a sacred site and tourist destination, however. It is also an active volcano around which four million people have settled, and it sits just 112 kilometers from the crowded streets of Tokyo. The last time Fuji erupted, in 1707, it sent out a cloud of ash that covered the capital city and darkened the skies for weeks. [E] Today, new information has some volcanologists concerned that Fuji may soon erupt again. According to Motoo Ukawa and his associates at the National Research Institute for Earth Science and Disaster Prevention, there has been an increase in activity under Fuji recently. This activity may be caused by low-frequency earthquakes. Understanding what causes these quakes may help scientists predict when Fuji will come back to life. In the meantime, locals living near Fuji hold special festivals each year to offer gifts to the goddess of the volcano – as they have for generations – so that she will not erupt and destroy the land and its people below. Mexico’s Threatening Mountain [F] Halfway across the globe from Fuji, Popocatepetl – one of the world’s tallest and most dangerous active volcanoes – stands just 70 kilometers southeast of Mexico City. Although the volcano (whose name means “smoking mountain”) has erupted many times over the centuries, scientists believe its last great eruption occurred around AD 820. In recent years, Popocatepetl is once again threatening the lives of the people near the mountain; in December 2000, almost 26,000 people were evacuated when El Popo – as Mexicans call the mountain – started to send out ash and smoke. As with all active volcanoes, the question is not if it will erupt again (an eruption is inevitable); the question is when it will happen. [G] “Every volcano works in a different way,” explains Carlos Valdes Gonzalez, a scientist who monitors El Popo. “What we’re trying to learn here are the symptoms signaling that El Popo will erupt.” These include earthquakes, or any sign that the mountain’s surface is changing or expanding. The hope is that scientists will be able to warn people in the surrounding areas so they have enough time to evacuate. A powerful eruption could displace over 20 million people – people whose lives can be saved if the warning is delivered early enough. [H] For many people living near El Popo – especially farmers – abandoning their land is unthinkable. As anyone who farms near a volcano knows, the world’s richest soils are volcanic. They produce bananas and coffee in Central America, fine wines in California, and enormous amounts of rice in Indonesia. [I] Today, many people continue to see El Popo as their ancestors did. According to ancient beliefs, a volcano can be a god, a mountain, and a human all at the same time. To appease El Popo and to ensure rain and a good harvest, locals begin a cycle of ceremonies that starts in March and ends in August. Carrying food and gifts for the volcano, they hike up the mountain. Near the summit, they present their offerings, asking the volcano to protect and provide for one more season.
