I have no problem with either of the questions. The second question does touch on the number (singular/plural) of collective nouns, which itself is a good area of discussion.
I disagree with Ms. Medina about her characterization of the two questions as having doubtful errors. I would be sympathetic to the second question because collective nouns can be difficult, but in this case, the use of committee is singular because it is acting as one body, not as a group of individuals. Only one decision is being made.
She does make a good case about the 'singular they' which we have have discussed in a previous thread. However, in the question provided, you don't need to use the 'singular they' because in this case, 'its' is available. In my opinion, the 'singular they' should be reserved for those cases where 'its' doesn't work.
I like the word synesis.
I disagree with her the flexibility of the comparative construct. The second part may be omitted, that's true, but that doesn't change the proper grammatical construct when it is included.
Good Luck
