Read the following article and select the best answer. Article: Vacation is a time for refreshment. In work, we are often called to think. Sometimes, it's good to give our brains a rest. Without a break, we may not be able to perform up to our potential. This can be a problem, not only for the employee, but for the employer as well. "The main benefit of vacation is for the worker to come back energized," says Weaver. "If they haven't had a break, then they're not coming back with new energy. They haven't had a chance to step back and get perspective , and come back with renewed enthusiasm." Long working hours without a break, insecurity about one's job, and other work-related worries can lead to burnout and stress. Humans can usually adapt to pressure, but not for a limitless amount of time. "It is a problem of relating good workers and having them loyal to the firm while they're _ ," says David Maume, PhD, professor of sociology at the University of Cincinnati. He says burnout can also affect employees' productivity, creativity, and effectiveness. In addition, high levels of stress are likely to be precursors to depression, which can hit both the employer and employee's pocketbook. Even people who manage to remain productive at work can have problems. If they're always at work, then they're not with their family and friends. If they're working while on vacation, for the time that they're on the job, they're not really present. An unbalanced emphasis on work can strain family and social life. When you come up for air, you may see that you're alone, or that your relationships have gone on without you. Question: What's the main benefit of a vacation? - The manager can be more creative. - The worker can come back with new energy. - The worker can adapt to pressure much better. - The worker can step back and get more excited.
The worker can come back with new energy.

Ques: Read the following article and select the best answer. Article: NASA-s New Horizons probe flew by Pluto this morning, sending back history's first up-close looks at the vast freezing-cold world. Closest approach came at 7:49 a.m. EDT. To celebrate, NASA gave out the latest photo of Pluto. It showed a reddish world with an amazing heart-shaped feature on its surface. After today's close encounter, all the nine solar system's traditionally recognized planets have now been visited by a spaceship-a huge project begun in 1962 when NASA's Mariner 2 probe flew past Venus, a planet in the solar system. More than l,200 scientists, NASA guests and important persons, including 200 reporters, watched the flyby live at New Horizons' mission control center. That close encounter has been a long time coming. The$723 million New Horizons mission launched in January 2006 but began taking shape in 1989. "New Horizons is'a capstone mission'," Glen Fountain, mission project manager told Space, com. "It is the first completion of the observations of our solar system. It-s giving us a new idea about how we human beings fit into the universe." New Horizons "faced a crazy number of challenges," Stern, a driving force behind New Horizons said, "So many people stuck with this for so long. They got knocked down; they stood up. They got knocked down again; they stood up again." In a coincidence, today's close approach falls on the 50th anniversary of the first flyby of Mars, another planet, which was completed by NASA-s Mariner 4 spaceship. There are no longer nine officially recognized planets, of course. The International Astronomical Union regarded Pluto as "a dwarf planet" in 2006 in a decision that remains controversial today. Question: Glen Fountain may probably agree that _ . - it is the most difficult to land on Pluto in the solar system - New Horizons mission is a long and troublesome project - their strong determination leads to the successful flyby - people are likely to find new ways to fit into space
Ans: people are likely to find new ways to fit into space
