Read the following article and select the best answer. Article: Warm water freezes more quickly than cold water. Sir Francis Bacon said that almost four hundred years ago. But few people believed him until 1970. In that year a Canadian scientist George Kill proved the English professor was right. Dr Kill filled an open oil pail with cold water. He filled another with warm water. He put both in the same low temperature. The warm water froze first. The lack of covers on the pails is the secret. Some of the warm water changed into vapor. This meant that less of the warm water was left to be frozen. And so the warm water froze faster than the cold water even though it had a greater temperature drop to make. Question: What Sir Francis Bacon said was right, but people didn't believe him until _ . - late in the 19th century - early in the 20th century - three years ago - late in the 20th century
late in the 20th century

Read the following article and select the best answer. Article: Orcas, or killer whales, are the largest of the dolphins and one of the world's most powerful animals feeding on meat. They feast on marine mammals such as seals, sea lions, and even whales, employing teeth that can be four inches (ten centimeters) long. They are known to grab seals right off the ice. They also eat fish, squid , and seabirds. Though they often frequent cold, coastal waters, orcas can be found from the polar regions to the Equator . Killer whales hunt in deadly groups, family groups of up to 40 individuals. There appear to be both permanent and temporary group populations of killer whales. These different groups may hunt different animals and use different techniques to catch them. Permanent groups tend to prefer fish, while temporary groups target marine mammals. All groups use effective, cooperative hunting techniques that some are similar to the behavior of wolf packs. Whales make a wide variety of communicative sounds, and each group has various noises that its members will recognize even at a distance. They use echolocation to communicate and hunt, making sounds that travel underwater until they meet objects, then reflect back, showing their location, size, and shape. Killer whales are protective of their young, and other adolescent females often assist the mother in caring for them. Mothers give birth every three to ten years, after a 17-month pregnancy. Killer whales are immediately recognizable by their special black-and-white coloring and are the intelligent, trainable stars of many aquarium shows. Killer whales have never been widely hunted by humans. Question: Killer Whale are often seen in some aquarium shows because _ . - they are able to be trained - they have special body colors - they must be protected - they have never been hunted
they are able to be trained

Q: Read the following article and select the best answer. Article: In prefix = st1 /America, drivers' education is part of high school. Every student in his or her second year of high school is required to take a course in drivers' education. However, unlike other courses, it isn't given during the regular school year. Instead, it is a summer course. The course is divided into two parts: class time for learning the laws and regulations, and driving time for practice. The students study the basic traffic laws they must know to pass the written driving test, which is given to anyone who wants to get a driver's license. Driving time is a chance for the students to sit behind the steering wheel and practice all kinds of skills that are required to drive a car. Each student is required to drive for a total of six hours. The students are divided into groups of four. The students and the instructor go out driving for two hours. Thus, each student gets half an hour of driving time per outing. The instructor and the "driver" sit in the front seats and the other three students sit in the back. The cars for drivers' education are different from other ears. In this kind of car there are two sets of brakes, one on the driver's side and the other on the instructor; s side. Thus, if the student driver runs into difficulties, the instructor can take over. This kind of car also has another special feature. On the rear window of the car is a sign that reads: STUDENT DRIVER. That lets nearby drivers know that they should be more careful because the student driver isn't very experienced. After the student has passed the drivers' education course and reached the proper age to drive, they can go to a designated state office to take the driving test, which is made up of an eye examination, a written test, and a road test. The student must pass all the three tests in order to get a driver's license. If the student does well in the drivers' education class, he or she will have no problem passing the test with flying color1s and getting licensed. Question: Which of the following is TRUE according to the passage? - Students who take the driving lessons don't need to learn laws and regulations. - The car for driver's education has a sign on the rear window. - Every student can pass the driving test only if he/she takes a course in driver's education. - The road test in the driving test is more important than the other two ones.
A: The car for driver's education has a sign on the rear window.
