Answer: 1a: âcomb our headsâ and âgot on my mark, bringing my eyes back to the bookâ
Explanation: 1a: This is an idiom, as you do not actually comb your head, but rather your hair.
1b: No-one goes to a specific mark as theyâre about to read a book, and you donât (and physically canât) drag your eyes to said book.
Hope this helped! Have a marvellous day!
