Critical Reasoning

focusgmat wrote:Students who perform average work in school sometimes receive higher grades than they actually deserve. These students are able to convince teachers that they truly enjoy the subject matter, are stimulated by the lectures, or have a personal interest in the instructor. These students must be careful, however, because exaggerated efforts may backfire.
If the statements above are true, which of the following draws the most reliable conclusion from the paragraph?

Best way to do question you find difficult is through process of elimination

1. Students are dishonest when it comes to grades. -- This is generalization , Students may or may not
2. Teachers may give grades to students for reasons other than classroom performance. -- These students are able to convince teachers that they truly enjoy the subject matter, are stimulated by the lectures, or have a personal interest in the instructor -so This is correct
3. Good students will seldom resort to trickery in achieving good grades. - May or may not again
4. Teachers want to help their students to excel in the classroom. - This not the conclusion of the arguments
5. The perceptions of average students are important in achieving good grades. - Not true.. perceptions doesn't matter

Please explain as to how I need to attack 'draw a conclusion' questions and as such how to attack the arg above. Aren't these type of questions similar to inference questions. Please help.
