下面小编就为大家整理了GWD逻辑TN-18的最后两道题目，大家可以认真研究一下，一定会对自己有帮助的。
Q30:
The ancient Nubians inhabited an area in which typhus occurs, yet surprisingly few of their skeletons show the usual evidence of this disease. The skeletons do show deposits of tetracycline, an antibiotic produced by a bacterium common in Nubian soil. This bacterium can flourish on the dried grain used for making two staples of the Nubian diet, beer and bread. Thus, tetracycline in their food probably explains the low incidence of typhus among ancient Nubians.
古努比亚人居住的地方曾经发生过斑疹伤寒，但是让人意外的是只有极少的骸骨的有得了这个病的迹象。这些骸骨还呈现出四环素的沉淀物，这是种常见的努比亚的土地能产生的一种细菌抗生物。这种细菌可以在努比亚人的两种主食(啤酒和面包)中的干谷类中发挥作用。因此，努比亚人食物中的四环素可能就是没有很多古努比亚人得斑疹伤寒的原因。
Which of the following is an assumption on which the argument relies?
Infectious diseases other than typhus to which the ancient Nubians were exposed are unaffected by tetracycline. 四环素对于其它病有没有效果不在读者讨论范围，此题讨论的仅是低斑疹伤寒发病率和食物中的四环素的关系。
Tetracycline is not rendered ineffective as an antibiotic by exposure to the processes involved in making bread and beer. 在食物制作过程中四环素不会变得无用。也就是说虽然有四环素，但如果加热或其它烹调过程可以让它无效，那即使食物中含了再多的无效四环素，也不会防治斑疹伤寒，那么低发病率就有其它原因。这个选项把这个可能排除掉。正确。
Typhus cannot be transmitted by ingesting bread or beer contaminated with the infectious agents of this disease. 斑疹伤寒会怎么传染不是讨论范围，判断这个选项无关还有一点：它没有包括一个重要因素：四环素。也没有其它信息可以替代四环素做出低发病率的解释。
Bread and beer were the only items in the diet of the ancient Nubians which could have contained tetracycline.现在讨论的仅是四环素和斑疹伤寒的关系问题，而且在主食中是含四环素的。其它食物含没含都不影响前提。
Typhus is generally fatal. 斑疹伤寒致命，但是古努比亚人的发病率却低。这就导致了人们去想为什么会出现这种情况。这句话可以加在题干中间当插曲，但是却和问题无关。
Q38:
A survey of entrepreneurs who started companies last year shows that while virtually all did substantial preparatory research and planning, only half used that work to produce a formal business plan. Since, on average, the entrepreneurs without formal plans secured the capital they needed in half the time of those with plans, these survey results indicate that, in general, formal plans did not help the entrepreneurs who produced them to secure the capital they needed.
在一个针对去年成立企业的创立人的调查中显示，尽管几乎所有人都做了相当的准备调查和计划工作，但是只有一半人是根据这些工作来确定了一个正式的商业计划的。因为，一般来讲，没有正式商业计划的企业家用了相当于有计划的一半的时间就保证了其资金需要以。这个调查显示，总体来讲，正式的商业计划对于企业家保证资金方面没什么用。
Which of the following, if true, most seriously weakens the argument?
Companies started by entrepreneurs who had used formal business plans to attract investment were on the whole as profitable in their first year as were companies started by entrepreneurs who had not produced such plans. 现在只在讲有正式的商业计划和成立期的资金保证之间的关系问题，成立后谁赚钱不在讨论范围。
In surveys of entrepreneurs who have attempted without success to raise sufficient capital, more than half of the respondents indicate that they have produced a formal business plan. 这不是说计划的确没有吗?我们要的可不是这个答案。
Among the entrepreneurs surveyed, those who did not produce formal business plans sought and received a much larger proportion of their capital from investors with whom they had a long-standing business relationship. 就是说得到资金支持不是因为没计划，没计划的原因只是因为资金从熟人那儿来，所以才不需要计划。正确。
The entrepreneurs surveyed who did not produce a formal business plan spent nearly as much time doing preparatory research and planning as the entrepreneurs who produced plans. 这儿只在谈有无计划对于保证创立资金关系问题，之前的准备工作无关。
The entrepreneurs who produced business plans generally reported later that the process of writing the plan had increased their confidence that their company would succeed. 计划的除了吸引资金外也许还有其它作用，但这个和问题无关。
