Earth's seasons, such as spring or summer, occur on Mars too Because these seasons exist, it may be possible for (39) _ and other higher life forms to
be found on Mars
Astronomers also think that perhaps a small amount of water vapor could
be found on Mars In 1887, an Italian astronomer, Giovanni Schiaparell,
discovered marking on Mars' surface These markings looked like canals This finding (40) _ astronomers to believe that since water exists on Mars, life forms could exist as well However, there are others who feel that life on Mars is not possible This is because there is little or no (41) _ of
oxygen on the planet In 1965, the Martiner IV capsule managed to take

In a study of aspirin's effect on blood clotting in which abstinence from
chocolate was required, a large proportion of participants broke the rules
Their "offence" led to what is believed to be the first biochemical
evidence that a few squares of chocolate a day can almost halve the risk of heart attack death by decreasing the tendency of tiny particles (or platelets) to clot in narrow blood vessels
"What these chocolate offenders taught us is that the chemical in cocoa
beans has a biochemical effect similar to aspirin in reducing platelet clumping, which can be fatal if a clot forms and blocks a blood vessel, causing a heart attack," said Diane Becker from Johns Hopkins University in Maryland, USA, who led the study
Becker cautions that this discovery should not become an excuse to
indulge in large amounts of chocolate frequently, since chocolate also contains
high amounts of sugar, butter and cream However just a few squares of dark chocolate the purest form may be just what the doctor ordered
For almost 20 years researchers have known that chemicals, called
flavonoids, most common in dark chocolate, help blood flow and lower blood pressure
Trang 5This new finding, presented at the American Heart Association's annual scientific sessions in Chicago this week, identifies the effect of everyday doses
of chocolate found in regular foods such as hot chocolate or chocolate bars This differs from previous studies which have examined the effects of eating unrealistic doses of flavonoids, equivalent to several pounds of chocolate a day
"Eating a little bit of chocolate or having a drink of hot cocoa as part of a regular diet is probably good for personal health, so long as people don't eat too much of it, and too much of the kind with lots of butter and sugar," said Becker
In the study, 139 chocolate offenders were disqualified from a larger experiment which aimed to examine the effects of aspirin on blood clotting Before the study began, all participants were instructed to follow a strict
exercise and diet regimen and to refrain from smoking or using foods and
drinks known to affect blood-clotting activity, like caffeinated drinks, wine, grapefruit juice and, of course, chocolate
Platelet samples from both groups (offenders and non-offenders) were run through a mechanical blood vessel system designed to time how long it takes for platelets to clump together Chocolate lovers' samples were found to clot more slowly, on average taking 130 seconds to block the system Platelets from those who stayed away from chocolate clotted faster, taking an average of 123 seconds
43: According to the findings, what helps lower blood pressure?
A The most important ingredient in chocolate
