(2) (B) in San Antonio the river應改為the riverin San Antonio，因為比較對象前無法有限定修飾
(3) (C) 錯誤選項，因為the river無法與San Antonio比較
(4) (D) but為對等連接詞，此句語意不對

寫作技巧：

GMAT作文旨在分析題目結論、找出題目邏輯錯誤之處（至少需兩個），並加以論述。
1. Introduction
(1) Present Argument
(2) Present Assumptions / opinion against the argument

2. Main Body
分段落以範例、論述（思考不全面、時間不夠長、樣本數不夠多、因果關係不明...等可削弱其論點之處）點出題目邏輯錯誤之處，或是能修改的部分。
Extend assumptions by reasoning and providing evidence or counter examples to refute the argument.

3. Conclusion
Provide a summary of your analysis of the argument.
(Stay objective, you’re not asked to give personal views on the argument)
