为什么GWD前10题总是错那么多？+最新13套2个问题

现在做GWD，总是无法保证前10题正确率，怎么办呢？每次逻辑还错5题，还是提高不了。另外有两个问题请教大家：

GWD最新套题第5套，

第1题：

Q1:

1. and her lobbying for wage and hour reform was persistent,
2. and lobbying for wage and hour reform was persistent, so that
3. her lobbying for wage and hour reform persistent, that
4. lobbying for wage and hour reform was so persistent,
5. so persistent her lobbying for wage and hour reform, that

为什么选E，不应该在两个so中加and吗？是怎么个结构呢？

The irradiation of food kills bacteria and thus retards spoilage.  However, it also lowers the nutritional value of many foods.  For example, irradiation destroys a significant percentage of whatever vitamin B1 a food may contain.  Proponents of irradiation point out that irradiation is no worse in this respect than cooking.  However, this fact is either beside the point, since much irradiated food is eaten raw, or else misleading, since _______.

1. many of the proponents of irradiation are food distributors who gain from food’s having a longer shelf life
2. it is clear that killing bacteria that may be present on food is not the only effect that irradiation has
3. cooking is usually the final step in preparing food for consumption, whereas irradiation serves to ensure a longer shelf life for perishable foods
4. certain kinds of cooking are, in fact, even more destructive of vitamin B1 than carefully controlled irradiation is
5. for food that is both irradiated and cooked, the reduction of vitamin B1 associated with either process individually is compounded

答案选E，不理解irradiation is no worse in this respect than cooking.这句话，怎么解这种填原因的题呢？

谢谢大家！

上面这道逻辑题，irradiation is no worse in this respect than cooking

是指irradiation带来的副作用并不比cooking带来的副作用来的多，cooking 也一样会破坏食物中的维他命B1。

答案是说，假如食物同时被irratiated和cooked, 那么维他命B1的减少程度比两个程序分别带来的副作用加起来还要多的多。注意题目最后一句的 “or else misleading" 就是要你选如果irrated food 被cooked 的话会带来怎样的恶果.......

谢谢啊~
