Article: Nearly 60 million visitors flooded to the 384 national parks across America every year. And you won't have to wander far from home to enjoy one of these national treasures, with Michigan's Isle Royale National Park nearby. Located 56 miles from Copper Harbor on Michigan's Upper Peninsula, the park remains _ that can only be reached by tour boat. With the exception of the Rock Harbor Lodge, which offers both rooms with private baths and accommodations in the form of small cottages, the 572,000 acres that make up the 45-mile-long park are rough, threaded with hiking paths that lead to tents-only campsites. You are likely to see a deer crossing mist-covered ponds in search of breakfast, gaze bald eagles flying overhead, or hear a beaver clapping its tail on the water. If you are especially lucky, you might even glimpse a grey wolf, nearly dying out from hunting on the mainland. Plenty of hiking paths open the area to exploration. The 4-mile Stroll Path winds through various trees and offers a tour of the island's history, including prehistoric Indian mines. The Jungle Path leads to Scoville Point----a perfect picnic spot surrounded on three sides by the shining waters of Lake Superior. You can also rent a boat at the park's service center and row down the shore to the Rock Harbor Lighthouse. Here park's service employees use nets to show how lake fishes used to be caught by the original local people. Their catch ends up on the dinner menu at the Rock Harbor Lodge. The park is open from mid-April through October; Rock Harbor Lodge is open from Memorial Day weekend until just after Labor Day.
Answer: Food provided by Rock Harbor Lodge is shipped from outside.
What can we infer from the passage?

Article: For a long time people have believed that high self-esteem is the key to success. However, new research shows that focusing just on building self-esteem may not be helpful. In some cases, having high self-esteem can bring bad results if it makes you less likeable or more upset when you fail at something. "Forget about self-esteem," says one of the psychologists involved in the new research. "It's not the most important thing." This idea may sound a bit strange to you because studies also show that people with high self-esteem are less likely to be anxious, shy, or lonely than those with low self-esteem. In short, to feel good does you good. But, after reviewing about 18,000 studies on self-esteem, Roy Baumeister, a psychologist at Florida State University, has found that building up your self-esteem will not necessarily make you a better person. He believes that violent and evil people often have the highest self-esteem of all. He also said, "There's no evidence that kids with high self-esteem do better in school." All types of people have problems. "People with high self-esteem can have big egos that can make them less likeable to their peers," said Kathleen Vohs, a psychology professor at Columbia University. "People with high self-esteem tend to think more of themselves," Vohs says. People with low self-esteem are more likely to rely on their friends when they need help. Researchers say it is best to listen to and support other people. Find positive ways to contribute to society. If you fail at something, try to learn from the experience. The best therapy , as they suggest, is to recognize your faults, accept yourself, understand your weaknesses and then do something about them.
Answer: New research shows that high self-esteem may not be helpful.
What's the passage mainly about?

Article: Thousands of dead red-winged blackbirds fell from the sky in an Arkansas town on New Year's Eve after massive injuries, tests by Arkansas officials concluded on Monday. Some 5,000 birds mysteriously fell from the sky in Beebe, Arkansas after dark on New Year's Eve. "The birds suffered from acute physical injuries leading to internal hemorrhage and death. There was no sign of infectious disease," the Arkansas Game and Fish Commission said in a statement. The birds were otherwise healthy, it said. One theory is that birds were frightened by New Year's fireworks and flew into buildings or other objects. "Loud noises were reported shortly before the birds began to fall from the sky," the statement said, adding that blackbirds have poor night vision and seldom fly at night. Another theory was that severe weather such as lightning accounted for the loud noises but this was _ because the violent weather had already left the area. "We're leaning more toward a stress event," said Arkansas Game and Fish Commission spokesman Keith Stephens. The commission also is trying to determine what caused the deaths of up to 100,000 fish over a 20-mile stretch of the Arkansas River near a dam in Ozark, 125 miles west of Beebe. The fish were discovered on December 30. Stephens said the commission expected results on the fish tests in probably a month. Since almost all the fish were one species -- bottom-feeding drum, Stephens said, the test was very important. Stephens also said: "The events do not appear related." Both that section of the river and the air at the site of the bird deaths were tested for toxins . Beebe is a town of about 4,500 people located 30 miles northeast of the state capital.
