Okay I'll give you the excerpts I think you refer to (lines in brackets are options):
<span><span>1. Oh! my dear Mr. Bennet," as she entered the room, "we have had a most delightful evening, a most excellent ball. I wish you had been there. Jane was so admired, nothing could be like it. Everybody said how well she looked; and Mr. Bingley thought her quite beautiful, and danced with her twice! Only think of that, my dear; <span>(he actually danced with her twice! and she was the only creature in the room that he asked a second time. First of all, he asked Miss Lucas. I was so vexed to see him stand up with her!</span>)
</span><span>2. "His pride," said Miss Lucas, "does not offend me so much as pride often does, because there is an excuse for it. <span>(One cannot wonder that so very fine a young man, with family, fortune, everything in his favour, should think highly of himself. If I may so express it, he has a right to be proud.")</span>
<span>("That is very true," replied Elizabeth, "and I could easily forgive his pride, if he had not mortified mine."</span>)
</span><span>3. "Well,"
said Charlotte, "I wish Jane success with all my heart; and if she were
married to him to-morrow, I should think she had as good a chance of
happiness as if she were to be studying his character for a twelvemonth. <span>(Happiness in marriage is entirely a matter of chance.
If the dispositions of the parties are ever so well known to each other
or ever so similar beforehand, it does not advance their felicity in
the least.)</span> -- (<span>They
always continue to grow sufficiently unlike afterwards to have their
share of vexation; and it is better to know as little as possible of the
defects of the person with whom you are to pass your life.<span>") </span></span></span></span>
I think the answers are all the options of excerpts 1. & 2.
2. One cannot wonder that so very fine a young man, with family, fortune, everything in his favour, should think highly of himself. If I may so express it, he has a right to be proud."
"That is very true," replied Elizabeth, "and I could easily forgive his pride, if he had not mortified mine."
The saying "men are like steel, when they lose their temper they lose their worth?" means that a man in a rage has lost a valuable property (the ability to keep a cool head) just like steel looking it's valuable property (it's tempering) when it gets re-heated. The expression tell men that they should not lose their "temper".
