1. People who like to make jokes to make other people think he/she is funny but actually just cause him/her to be a jerk.

2. People who is very sophisticated and always know what to do in a certain situation. ie, everybody cheat on the exam so he/she does it too. The adj. of know better or is there a commom expression in English?

3. However, CT suffered from an aspect that once you learned how guards acted and reacted, you could pretty much ensure a kill or stealth on the entire level. There weren't near any situations where you had to think on your feet or other dynamic "that was neat" effects.

This is what I found using google, is it correct?

Being able to think quickly -- having answers to questions on the ready. Not having to sit down and ponder something for a long time. "We sent Elizabeth to face the committee because she can think on her feet."

Thank you.

I am not clear on your questions, Kanonathena.

I can say that #s 1, 2 and 3 all have glaring grammar errors; also, thinking on one's feet does indeed mean thinking quickly; having answers to questions at the ready; not having to sit down and ponder something for a long time.

Was there something else?

Sorry.

1. How to describe people who often make a lot of silly jokes just to make other people think he is funny?

2. How to describe people who are very sophisticated and always know how to take advantage of situation?

For example, everybody cheat on the exam so he/she does it too.

3. What's the difference between solved and resolved?

Thank you.
