Lost among the kitchens. I curse those sods.
1A - had a problem with the parsing too. I think Aristo is right.
(a) - the same, but then found I was pronouncing it incorrectly.
See Wikipedia - this site won't all the phonetic symbols.

The first vowel is pronounced as in "tee", whereas Haole tend to say it as in "tie".
So, two homophones - "in the mouth".
Again, quite a number of nice surface reads.
My faves: A - 10, 23. D - 6, 7, 15. IC - e, l.
For (b), I assume that "back" does double duty as head indicator & reversal.
