1. Read the entire question first. This enables you to get a better sense of the 'argument' and how best to approach the logic involved.
2. Read the entire argument as well. This enables you to better understand the logic involved and the likely conclusions.
3. Pay attention to key words, such as always or never (absolute terms) or sometimes or almost (relative terms).
4. In trying to use the process of elimination, you should consider dropping from consideration an answer choice if it goes beyond the contents (ie. scope) of the argument.
5. You should also consider eliminating choices that are more extreme (ie. using absolute terms).
