Practice GMAT Sentence Correction Question

There are three main issues being tested in this question.

(1) The phrase their home is redundant as the word their could be eliminated

(2) The phrase other tribal groups historically experienced (with its verb in the simple past tense) must be replaced with a phrase that uses the past perfect tense (i.e., historically had experienced). The past perfect tense must be used since we are dealing with two actions in the past where one action came before another (i.e., the historic ability to find food predated the decision to move). The word historically makes it clear that the ability to find food referred to the period of time before the individuals decided to move in 2007.

(3) The word less cannot be used with difficulties since difficulties can be counted and the proper word for countable items is fewer

1. the word their is redundant; the word less should be replaced by the word fewer; the simple past tense (experienced) should be replaced by the past perfect tense (had experienced)
2. the simple past tense (experienced) should be replaced by the past perfect tense (had experienced)
3. the word their is redundant; the simple past tense (experienced) should be replaced by the past perfect tense (had experienced)
4. many indigenous people...left home not in search of other tribal groups (as this option incorrectly states), but for land where other tribal groups historically had experienced fewer difficulties finding food
5. the unnecessary word their is properly eliminated; the past perfect tense is correctly used; the word fewer is used with countable items
