Dressed as a man and using the name Robert Shurtleff, Deborah Sampson, the first woman to draw a soldier's pension, joined the Continental Army in 1782 at the age of 22, was injured three times, and was discharged in 1783 because she had become too ill to serve.
听过之前的录音说was injured 和 was discharged并列，所以and前后都得有be 动词。。。但是我比较想问的是难道joined和后面两个不并列嘛。。。它就没加was呀，加了意思就不对了呀。 老师原谅我的智商有点儿不够用。。麻烦您再讲讲吧~

In countries where automobile insurance includes compensation for whiplash injuries sustained in automobile accidents, reports of having suffered such injuries are twice as frequent as they are in countries where whiplash is not covered.  Presently, no objective test for whiplash exists, so it is true that spurious reports of whiplash injuries cannot be readily identified.  Nevertheless, these facts do not warrant a conclusion that has been drawn by some commentators:  that in the countries with the higher rates of reported whiplash injuries, half of the reported cases are spurious.  Clearly, in countries where automobile insurance does not include compensation for whiplash, people often have little incentive to report whiplash injuries that they actually have suffered.

One of the limiting factors in human physical performance is the amount of oxygen that is absorbed by the muscles from the bloodstream.  Accordingly, entrepreneurs have begun selling at gymnasiums and health clubs bottles of drinking water, labeled "SuperOXY," that has extra oxygen dissolved in the water.  Such water would be useless in improving physical performance, however, since the only way to get oxygen into the bloodstream so that it can be absorbed by the muscles is through the lungs.
 
Which of the following, if true, would serve the same function in the argument as the statement in boldface?

Tanco, a leather manufacturer, uses large quantities of common salt to preserve animal hides.  New environmental regulations have significantly increased the cost of disposing of salt water that results from this use, and, in consequence, Tanco is considering a plan to use potassium chloride in place of common salt.  Research has shown that Tanco could reprocess the by-product of potassium chloride use to yield a crop fertilizer, leaving a relatively small volume of waste for disposal.
 
In determining the impact on company profits of using potassium chloride in place of common salt, it would be important for Tanco to research all of the following EXCEPT:

After several years of rapid growth, the healthy care company became one of the largest health care providers in the metropolitan area, while it then proved unable to handle the increase in business, falling months behind in its payment to doctors and hospitals.
我当时的想法有三个问题：第一，我觉得falling不合适，因为好像没有正在进行发工资的意思，而是先没法处理营业额增长后没法发工资的。第二，我想着it没有歧义，而且it说出来是不让人猜，比proving好了。第三，被it proves。。。。迷惑了，感觉读起来挺顺的，其实是不对的，现在明白了这一点。前两点请老师解答。谢谢：）
