请教OG11 ASSUMPTION 题

JQ1124

(50) If the country countinues to collect residential trask at current levels, land fillls will soon be overflowing and parkland will need to be used in orer to creat more space. Charging each hiusehold a fee for each pound of therefore protect the remaining country parkland. 该题问结论是在何前提中推出。 答案A中 Residents wukk redyce the amiunt of trash they out out for collection by reducing the number of oroducts they buy. 请问这个按照说也是GAP中新元素的出现填补这个GAP。 跟答案是 The collection fee will not induct residents to dump THEIR TRASH IN THE PARKLANDS illegally.

59 题中 大意是 Congress might make former  officials wait three years before working as lobbyists.An official argues that this rule would keep these people from wroking.这个题的假设前提，我觉得B 中Lobbyisits are typically people who have previously been high-levelgoverment officials. 不选这个理由是因为这个是充分条件而非必要条件吗？

77 ) R: the alarming fact is that 90% of the people in this country nwo report that thye know someone who is unemployed. S: But a normal, if niderate kevel of unemployeement is 5%woth one out of 20 workers unemployed. So at any given time if a person knows approximatly 50  workers,one or more will very likely be unemployed.  这个题目中 S的论点假设如何推理？

81）可恶的雷达题目，我一直不理解这题目。 A recent report  only 3% drivers on M equiped  with radar detectors, 33%of all  vehichles tickted for exceeding the speed limited were with Radar, 推出 vehicles with rader detactors are more likely to exceed the speed limit regular than are drivers who do not.  这个题目的答案怎么来考虑？ 为何是B，

ps 在lawyer 逻辑总结中：

ASSUMPTION的方法排除充分条件出现，必要条件不出现的情况。或充分条件一定能推出必要条件，或排除充分条件推不出必要条件的可能  ，不是很理解。

谢谢各位大N。
