Write a question about the following article.

I am very grateful that I chose to wear flats instead of heels . Went to 5 shows today . I could have seen 7 shows , but for some reason and distractions I ended up going to 5 ( 3 shows I ' sneaked ' in without a ticket ! ) .

Question:
Why were they thankful for their flats ?
Pick from: (i) None of the above choices . (ii) The flats were required under the show 's dresscode . (iii) Their flats allowed them to watch the shows comfortably . (iv) Their flats looked better on them than the heels .
