Answer choice A and conditional conclusions

@Dalaal, happy to help. Though it would be better than its current state, your revision of (A) would still be incorrect because the term "old" is undefined. However, if (A) said that "some people who are at least as old as Sims cannot effectively address the difficult issues facing the country," it could be correct. Remember, "some" means "at least one, possibly all." Does that make sense? Let us know if you have any other questions!
