Then shows Sequence:
this is correct, because then is used to describe a <em>sequence </em>of events. Example: "I ate cake <u>then </u>I went home."
Accept meant "excluding"
this is incorrect, because the word <em>except </em>means excluding. Accept is used in terms of "accepting something"
For example:
"All of us <u>except</u> john went to the park"
"The college chose to <u>accept</u> my application"
Than is comparative
this is correct, than can be a comparative word. For example:
"he is better <u>than</u> him at basketball"
Affect means to change
this is correct, affect is to make a change. For example:
"music can <u>affect</u> your mood"
Except means to receive
this is incorrect, except is not to receive, this is a common definition of "accept" except means to dis-include. Although I have already gave an example, here is another one:
"I like every color of the rainbow <u>except</u> orange"
An Effect is a result
this is correct, effect is a result.
"whining and crying has no <u>effect"</u>
