check these two problems,thank you guys~
70.The more television children watch,the less competent they are in mathematical knowledge.More than a third of children in the United States watch television for more than five hours a day;in South Korea the figure is only 7 percent.But whereas less than 15 percent of children in the United States understand advanced measurement and geometric concepts,40 percent of South Korean children are competent in these areas.Therefore,if United Stated children are to do well in mathematics,they must watch less television.
Which one of the following is an assumption upon which the argument depends?
C)Children who want to do well in davanced measurement and geometry will watch less television.
E)The instruction in advanced measurement and geometric concepts available to children in the United States is now substantially worse than that avaliable to South Korean children.
73.In Malsenia sales of classical records are soaring.The buyers responsible for this boom are quite new to calssical music and were drawn to it either by classical scores from television commercials or by theme tunes introducing major sports events on television.Audiences at classical concerts,however,are continually shrinking in Masenia.It can be cincluded from this that the new Malsenian Converts to classical music,having initially experienced this music as recorded music,are most comfortable with classical music as recorded music and really have bo desire to hear live performances.
The argument assumes which one of the following?
A)To sell well in Malsenia,a classical record must include at least one piece familiar from television.
B)At least some of the new Malsenian buyers of classical recorde have available to them the coupon of attending classical concerts.
C)The number of classical concerts performed in Malsenia has not decreased in response to smaller audiences.
D)The classical records available in Malsenia are for the nost part not recordings if actual public concerts.
E)Classical concerts in Malsenia are not limited to music that is really available on recordings.
In no.70,the answer is E,but i think C also can be a good assumption.
In no.73,the answer is C,but in my mind,we can't get the direct assume from C,though there is no better answer.
how do u think?I am waiting for ur suggestions,thank u.
