4. like the grassy fields and old pastures that the upland sandpiper needs for feeding and nesting when it returns in May after wintering in the Argentine Pampas, the sandpipers vanishing in the northeastern United States is a result of residential and industrial development and of changes in farming practices.
A. the sandpipers vanishing in the northeastern United States is a result of residential and industrial development and of changes in
B. the bird itself is vanishing in the northeastern United States as a result of residential and industrial development and of changes in

D. in the northeastern United States, sandpipers’ vanishing is due to residential and industrial development and to changes in
E. in the northeastern United States, the sandpipers’ vanishing, a result of residential and industrial development and changing
答案解析：
A. the sandpipers vanishing不是一個result。
B. correct。
C. that引導的名詞性從句描述的是一個事件與the grassy fields and old pastures不對等。
D. sandpipers’ vanishing事件與the grassy fields and old pastures不對等。由于like/unlike的比較相對嚴格，所以比較對 象應盡可能接近，所以把in the northeastern United States放在中間很awkward。
E. the sandpipers’ vanishing事件與the grassy fields and old pastures不對等;主句不完整，缺少謂語; development與changes平行，不與practices平行。
引申：
1. 比較：like/unlike的對比雙方需要遵循嚴格詞性、功能等的平行。
2. Due to可以用attributed to或caused by替代來權衡邏輯上是否合理，其次due to，similar to，differing from等有形容 詞性質的介詞，GMAT中一般不能出現在句首。
5. A scrub jay can remember when it cached a particular piece of food in a particular place, researchers have discovered, and tend not to bother to recover a perishable treat if stored long enough to have rotted.
A. tend not to bother to recover a perishable treat if
B. they tend not to bother recovering a perishable treat
C. tending not to bother to recover a perishable treat it
D. tends not to bother recovering a perishable treat
88
E.tends not bothering to recover a perishable treat it
答案解析：
A. tend單復數錯誤，應為單數，對應主語 A scrub jay;if從句缺主語。即便加入代詞it，也將會荒謬的指代jay，而 不是treat。Bother to do/bother doing都是對的。
B. they指代不明。
C. 少謂語，It多余。
D. Correct。tends使用正確，主謂一致。bother doing用法idiomatic, stored后置定語修飾treat正確。
E. tends使用正確，和can remember 并列。tend doing沒有這種用法。It多余。
引申點：
主謂一致(Agreement)，平行對稱(Parallelism)
1. 主謂一致
2. 固定搭配：
Tend用法
Tend to do sth -- If something tends to happen, it happens often and is likely to happen again
Tend to sb/sth 照顧
6. Not only did the systematic clearing of forests in the United States create farmland (especially in the Northeast) and gave consumers relatively inexpensive houses and furniture, but it also caused erosion and very quickly deforested whole regions.

D. The systematic clearing of forests in the United States created farmland (especially in the Northeast) and gave consumers relatively inexpensive houses and furniture, but it also
E. The systematic clearing of forests in the United States not only created farmland (especially in the Northeast), giving consumers’ relatively inexpensive houses and furniture, but it
答案解析：
A. not only 位于句首時，所引導的句子要用倒裝，give 和 create 是 and 連接的兩個并列成分，而時態已經被 did 提 前，只能用原形。所以這里 gave 錯。But it also 沒有錯。
B. Which 定語從句修飾 farmland，邏輯意義錯誤，是 systematic clearing 給了 consumers houses and furniture，不是farmland。
C. But also 之前無謂語，片段。
D. Correct;But it also,轉折前后句，說明 systematic clearing 既帶來了好東西，也帶了壞東西，also 的使用，精妙。
E. Giving 修飾 created,改變了原來的句意：并列的兩個動作;Not only…but…也可以.
7. The commission’s office of compliance, inspections, and investigations plans to intensify its scrutiny of stock analysts to investigate not only whether research is an independent function
