Read the following article and select the best answer. Article: Bears and humans often meet in National Parks. Although campers and hikers are warned not to feed the bears, many people ignore these warnings and feed the beasts anyway. When bears are used to people's food, problems soon arise. Bears like to eat a large variety of things, both meat and vegetable. Without human assistance, bears live nicely on roots, twigs, leaves of trees, insects and small animals. With people around, the bears' tastes quickly expand to include sandwiches, hot dogs, hamburgers, and anything else they can temp humans into giving up. Bears often develop clever strategies for getting people to let go their food supplies. More often than not, an unsuspecting hiker has taken off his or her pack for a rest only to have a bear charge out of the woods, grab the pack and quickly disappear into the underbrush with it. Hanging the pack on a tree branch won't help. Bears have been known to climb up, jump off, and catch the pack on the way down. One mother bear stretched up with her baby on her shoulders to reach a pack stored on a pole. Many bears threaten people into giving up their supplies. Although a bear is unlikely to attack a person and would probably run away if screamed at, few people are willing to do so. Most people drop the pack and run the other way. This, of course, delights the bear. In some places, the Park Service installed some metal barrels with lids to help campers keep their supplies safe from bears. Although the bears were unable to open these containers, the effort was less than successful. Most campers, unable to tell the metal drums from rubbish cans, never used them for the intended purpose. Question: Bear-proof containers didn't work because_. - bears were clever enough to get the food in them - they were left open in the open air - people were not sure of their use - they were once used as rubbish cans
(Answer)
people were not sure of their use

Read the following article and select the best answer. Article: The origins of blues are not unlike the origins of life. For many years it was recorded only by memory, and relayed only live, and in person. The blues were born in the North Mississippi Delta following the Civil War. Influenced by African roots, field hollers , ballads, church music and rhythmic dance tunes called jump-ups evolved into a music for a singer who would engage in call-and-response with his guitar. He would sing a line, and the guitar would answer. From the crossroads of Highways 61 and 49, and the platform of the Clarksdale Railway Station, the blues headed north to Beale Street in Memphis. The blues have strongly influenced almost all popular music including jazz, country, and rock and roll and continue to help shape music worldwide. Bad luck and trouble are always present in the Blues. Relentless rhythms repeat the chants of sorrow, and the pity of a lost soul many times over. The blues form was first popularized about 1911-14 by the black composer W.C. Handy. However, the poetic and musical form of the blues first crystallized around 1910 and gained popularity through the publication of Handy's Memphis Blues(1912) and St.Louis Blues(1914). Instrumental blues had been recorded as early as 1913. During the twenties, the blues became a national craze. Mamie Smith recorded the first vocal blues song, Crazy Blues in 1920. In the early 1960s, the urban bluesmen were "discovered" by young white American and European musicians. Many blues-based bands brought the blues to young white audiences. Since the sixties, rock has undergone several blues revivals. Some rock guitarists have used the blues as a foundation for offshoot styles. The latest generation of blues players like Robert Cray and the late Stevie Ray Vaughan, gracing the blues tradition with their incredible technicality , have drawn a new generation listeners to the blues.
