Adjective is a describing word...its BROKEN
Dude, the word isn't underlined. From what I can... assume, the word that's supposed to be underlined is "riddled."
The best option is, Perforated. The comparison to a sponge makes it obvious too, because sponges have holes. Check out the definition for Perforated below.
Definition: pierce or make holes in
"a perforated appendix"

The correctly punctuated sentence is the first one "Will we ever get there?". It´s a direct question, so the question mark is obligatory at the end and it replaces a period in case the sentence finishes there.
The second part "Sandy asked fretfully", must be preceded by a comma because what comes after is the person who came up with the question. However, if it is a quoted question (it doesn´t seem to be the case here), which end in mid sentence, the question mark replaces a comma.
