¡¡¡¡Which one of the following is best supported on the basis of the information above£¿
¡¡¡¡£¨A£©If the upward trend in out-shopping continues at a significant level and the amounts paid by the government for Canadian social services are maintained£¬ the Canadian goods-and-services tax will be assessed at a higher rate.
¡¡¡¡£¨B£©If Canada imposes a substantial tariff on the goods bought across the border£¬ a reciprocal tariff on cross-border shopping in the other direction will be imposed£¬ thereby harming Canadian businesses.
¡¡¡¡£¨C£©The amounts the Canadian government pays out to those who provide social services to Canadians are increasing.
¡¡¡¡£¨D£©The same brands of goods are available to Canadian shoppers across the border as are available in Canada.
¡¡¡¡£¨E£©Out-shopping purchases are subject to Canadian taxes when the purchaser crosses the border to bring them into Canada.
¡¡¡¡2. Left-handed persons suffer more frequently than do right-handed persons from certain immune disorders£¬ such as allergies. Left-handers tend to have an advantage over the right-handed majority£¬ however£¬ on tasks controlled by the right hemisphere of the brain£¬ and mathematical reasoning is strongly under the influence of the right hemisphere in most people.
¡¡¡¡If the information above is true£¬ it best supports which of the following hypotheses£¿
¡¡¡¡£¨A£© Most people who suffer from allergies or other such immune disorders are left-handed rather than right-handed.
¡¡¡¡£¨B£© Most left-handed mathematicians suffer from some kind of allergy.
¡¡¡¡£¨C£© There are proportionally more left-handers among people whose ability to reason mathematically is above average than there are among people with poor mathematical reasoning ability.
¡¡¡¡£¨D£© If a left-handed person suffers from an allergy£¬ that person will probably be good at mathematics.
¡¡¡¡£¨E£© There are proportionally more people who suffer from immune disorders such as allergies than there are people who are left-handed or people whose mathematical reasoning ability is unusually good.
