A majority of the international journalists surveyed view nuclear power stations as unsafe at present but that they will, or could, be made sufficiently safe in the future. (A) that they will, or could, (B) that they would, or could, © they will be or could (D) think that they will be or could (E) think the power stations would or could Skeleton of the sentence: A majority.............view(V1)..............but...........(V2).. We need a verb after BUT. ==> Eliminate A. B, and C. Between D and E: See the following sentences: --> I thought that he would come tomorrow. --> They think that he will come tomorrow. Note: When the verb before that is past tense, we need WOULD. If we have a verb in present tense, we need to use WILL. ==> Eliminate E. Answer: D They in D: They may refer to journalists or power stations. Journalists will be made unsafe. power stations will be made unsafe. Which one makes sense? Of course two. Conclusion: They in D is not ambiguous.

Answer is E, but the explanations offered are not full. Split ONE: Evidence of X VS Evidence that X "Evidence of X" means X's evidence. B. Evidence of the North American Indians who.... => North American Indians' evidence. Is it eh evidence of individuals? Nope. It changes the intended meaning of the sentence. D. Evidence of the North American Indians and their development {Evidence of X and of Y} => Same logic can be applied as it is in case of B. A. Indians developed calendars basing them There are at least two problems in this option: 1. Them is ambiguous because both calendars and Indians are plural. Which one is the antecedent of THEM? 2. Basing retains the "Indians" as its subject, meaning Indians are based on blah blah........... It changes the intended meaning of the sentence. Another example: They have done the work writing on the wall. Who have done the writing? They. Option C:\ A “calendar stick” carved centuries ago by the Winnebago tribe may provide the first evidence of the development of advanced full-year calendars by North American Indians, basing them Skeleton: A calendar stick may provide evidence of X, basing them........... COMMA + VERB-ING modifies the entire preceding clause and retains the subject of the clause as it's subject. Now, A stick is based on-------------Incorrect. Another obvious error is "Them", which does not have clear referent. Answer is thus E, which free from errors. Thanks.

Difference between So X as to Y and So X that Y. reference from official guide: 1. Official guide 10th edition has used it correctly in one of the sentence corrections questions. 2. Official guide 11th edition has mentioned that So x as to Y is no more in use. 3. So X that Y is more commonly used in GMAT Land as well as in general English than So X as to Y. Examples from Nytimes: I have searched the nytimes with the words "So long as to.." and with many more, but no result has been found with such entry. Again, i have searched google with "so long as to...'', but no such result appear. Therefore, it can be easily concluded that 'so X as to y" is used rarely. Just use so X that Y. About the difference: If you are the hunter for the answer of your questions, here is the answer: bot of them are used in case of cause and effect. HTH.
