Read the following article and select the best answer. Article: People typically wash their hands seven times a day in the United States, but they do it at a far higher temperature than is necessary to kill germs , a new study says. The energy waste is equivalent to the fuel use of a small country. Amanda R. Carrico, a research assistant professor at the Vanderbilt Institute for Energy and Environment in Tennessee, told National Geographic that hand washing is often "a case where people act in ways that they think are in their best interest, but they in fact have inaccurate beliefs or outdated perceptions." Carrico said, "It's certainly true that heat kills bacteria, but if you were going to use hot water to kill them it would have to be way too hot for you to tolerate." Carrico said that after a review of the scientific literature, her team found "no evidence that using hot water that a person could stand would have any benefit in killing bacteria." Even water as cold as 40degF (4.4degC) appeared to reduce bacteria as well as hotter water, if hands were scrubbed, rinsed and dried properly. Using hot water to wash hands is therefore unnecessary, as well as wasteful, Carrico said, particularly when it comes to the environment. According to her research, people use warm or hot water 64 percent of the time when they wash their hands. Using that number, Carrico's team calculated a significant impact on the planet. "Although the choice of water temperature during a single hand wash may appear unimportant, when multiplied by the nearly 800 billion hand washes performed by Americans each year, this practice results in more than 6 million metric tons of CO2 equivalent emissions annually," she said. The researchers published their results in the July 2013 issue of International Journal of Consumer Studies. They recommended washing with water that is at a "comfortable" temperature, which they noted may be warmer in cold months and cooler in hot ones. Question: What can we learn from the passage? - It's necessary and useful for people to wash their hands frequently every day. - We can wash our hands with water that is at a "comfortable" temperature. - Using cold water to wash hands is necessary and much healthier. - Hot water can't kill germs.
(Answer)
We can wash our hands with water that is at a "comfortable" temperature.

Read the following article and select the best answer. Article: Paula Radcliffe, chasing a third London marathon title , says she has become a stronger person after her terrible experience at the 2004 Athens Games. Radcliffe, who failed to complete the Olympic marathon and the 10,000m last August, said: "Athens made me a stronger person and it made me care less about criticism." "In the past I wanted to please everyone, but now I am going to listen even more to the people around me." She didn't care about criticism made at the weekend by Liz McColgan, who felt Radcliffe should have rested and let her body recover after her failure in Athens. "Liz is someone I look up to but she hasn't spoken to me since last year and if she really cared for me, I'm sure she would have contacted me." Instead Radcliffe won the New York City marathon just 11 weeks after Athens. "In New York I wasn't in my best state but I did know I was good enough to win the race." Radcliffe insisted her only goal in Sunday's race would be winning a third title and not chasing world records. However, Radcliffe has not ruled out in the future chasing her "final" world record time and questioned sayings that marathon runners have the ability in their career to produce only four or five world-class times. "I don't think that--although _ ," said Radcliffe. "That changes from person to person." Radcliffe is sure she can better her winning London 2003 performance at some point in the future. Following a successful three-month training period in the United States, the 31-year-old will chase a third title on Sunday after her first victory in 2002 and again 12 months later. Radcliffe clocked a time of 2:18:56 in her first 42.2-kilometer race three years ago. Afterwards she set a "mixed course" mark of 2:17:18 five months later in Chicago before lowering that to a time of 2:15:25 in the 2003 London event. Question: Radcliffe's failure in Athens made her _ . - develop respect for Liz. - love people around her more. - rest for five months. - face criticism calmly.
(Answer)
face criticism calmly.
