请大家看两道题
一、Suncorp, a new corporation with limited funds, has been clearing large sections of the tropical Amazon forest for cattle ranching. This practice continues even though greater profits can be made from rubber tapping, which does not destroy the forest, than from cattle ranching, which does destroy the forest。
A The soil of the Amazon forest is very rich in nutrients that are important in the development of grazing lands.
OG的分析：This statement gives a reason why cattle ranching in the Amazon might be more profitable than one might otherwise think it would be. However, we already know from the passage that rubber tapping would be more profitable than cattle ranching. So, this answer choice does not help explain why cattle ranching might be preferable to rubber tapping.


二、Enterprise Bank currently requires customers with checking accounts to maintain a minimum balance or pay a monthly fee. Enterprise plans to offer accounts with no monthly fee and no minimum-balance requirement; to cover their projected administrative costs of $3 per account per month they plan to charge $30 for overdrawing an account. Since each month on average slightly more than 10 percent of Enterprise's customers overdraw their accounts, bank officials predict the new accounts will generate a profit.
E Customers whose checking accounts do not have a minimum-balance requirement are more likely than others to write checks for small amounts
OG的分析：This suggests that a check written by one of these customers is more likely to be for a small amount and is therefore somewhat less likely to cause an overdraft (unless such customers typically have small checking balances, which we are not told). If there were many such customers for the proposed new account, the overdraft rate might be less than 10 percent; this would indicate that the new account might not turn out to be profitable.


第一题的A选项，暗示了放牧的盈利能力比预期的好，但是OG答案明确说了再好也不会比rubber的好，因为材料中已经确定了rubber的盈利更好。
第二题的E选项，暗示了支票账户的客户超支的可能性更小，进而new plan的盈利能力更差，此时OG答案说可能会比10%更差，但是材料中明确了 ”since“有10%的客户会超支。
所以我的问题是，分析选项的时候，到底能不能突破材料中给的信息的限制？如果可以的话，对于第一题的A，假设放牧的盈利能力超过rubber的话，那么就成了正确选项之一了。
大家怎么认为的呢？
