It seems like most of the time the correct answer attacks an unstated assumption, but I can never immediately identify that assumption and end up choosing a tricky wrong answer.
Can someone please give me some advice?! these are killing me... ><
On these Qs, you're most likely looking at a stimulus that is using some sort of cause-effect relationship, so you'll either strengthen or weaken that relationship.
For example, a study indicates that the number of smokers in a town decreased after the town passed a $1/pack tax on cigarettes. Therefore, the tax caused the decrease.
To strengthen this, you'll want to show same cause-same effect, no cause-no effect, or potentially outside info that eliminates an alternative explanation (e.g, another town recently passed a $1/pack tax, and the number of smokers decreased substantially).
To weaken this, you'll do just the opposite: same cause-no effect, no cause-same effect, or outside info that shows an alternative explanation is plausible (another town recently passed a $1/pack tax, and the number of smokers did not decrease/actually increased).
You really need to dig down and determine the realtionship between the premises and the conclusion and what support is being given.
