Article: Science can't explain the power of pets,but many studies have shown that the company of pets can help lower blood pressure and raise chances of recovering from a heart attack,reduce loneliness and spread all-round good cheer. Any owner will tell you how much joy a pet brings.For some.an animal provides more comfort than a husband/wife.A 2002 study by Karen Allen of the State University of New York measured stress 1evels and blood pressure in people-half of them pet owners-while they performed 5 minutes of mental arithmetic or held a hand in ice water.Subjects completed the tasks alone,with a husband/wife,a close friend or with a pet.People with pets did it best.Those tested with their animal friends had smaller change in blood pressure and returned most quickly to baseline heart rates.With pets in the room,people also made fewer math mistakes than when doing in front of other companions.It seems people feel more relaxed around pets,says Allen,who thinks it may be because pets don't judge. A study reported last fall suggests that having a pet dog not only raises your spirits but may also have an effect on your eating habits.Researchers at Northwestern Memorial Hospital spent a year studying 36 fat people and their equally fat dogs on diet-and-exercise programs;a separate group of 56 people without pets were put on a diet program.On average,people lost about 11 pounds,or 5% of their body weight.Their dogs did even better,losing an average of 12 pounds,more than 15%of their body weight.Dog owners didn't lose any more weight than those without dogs but,say researchers,got more exercise overall-mostly with their dogs--and found it worth doing. Question: We 1earn from the text that a person with heart disease has a better chance of getting well if _ . - he has a pet companion - he has less stress of work - he often does mental arithmetic - he is taken care of by his family

To test their skills in recognizing a suspect, he shows the first blonde a picture for5 seconds and then hides it. "This is your suspect, how would you recognize him?" The first blonde answers, "That's easy, we'll catch him fast because he only has one eye!" The policeman says, "Well...uh...that's because the picture shows his profile." Slightly confused by this ridiculous response, he flashes the picture for 5 seconds at the second blonde and asks her, "This is your suspect, how would you recognize him?" The second blonde giggles, flips her hair and says, "Ha! He'd be too easy to catch because he only has one ear!" The policeman angrily responds, "What's the matter with you two? Of course only one eye and one ear are SHOWING because it's a picture of his profile!! Is that the best answer you can come up with?" Extremely frustrated at this point, he shows the picture to the third blonde and in a very testy voice asks "This is your suspect, how would you recognize him?" He quickly adds, "Think hard before giving me a stupid answer." The blonde looks at the picture intently for a moment and says, "Hmmmm...the suspect wears contact lenses." The policeman is surprised and speechless because he really doesn't know himself if the suspect wears contacts or not. "Well, that's an interesting answer...wait here for a few minutes while I check his file and I'll get back to you on that." He leaves the room and goes to his .office, checks the suspect's file in his computer, and comes back with a beaming smile on his face. "Wow! I can't believe it...it's TRUE! The suspect does in fact wear contact lenses. Good work! How were you able to make such an acute observation?" "That's easy," the blonde replied. "He can't wear regular glasses because he only has one eye and one ear." Question: Why did the policeman show a picture to the three blondes? - To inquire about their relationship with the suspect. - To test their potential of being detectives. - To train them as qualified police officers. - To show the skills in recognizing a suspect.
To test their potential of being detectives.
