Is this cloze test correct?

Hi,

Could somebody please help me with this cloze test, I think it has some errors.
I filled in the ones I was sure about and just left the ones I thought had errors.

At noon, just as I was leaving my friend's office, it suddenly came to my mind that I had no idea where I had parked my car. I could ___1____ go up to a policeman and tell him that I had lost a small green car somewhere! I would simply have to look for it myself. I walked down street after street. I examined each car closely and was very much ____2____ to see a small green car just behind an old car. But how ____3___ I was to discover that though the car was exactly like my own, it belonged to someone else.

1- 1) hardly 2) kindly 3) merely 4) truly
2- 1) available 2) comfortable 3) miserable 4) responsible
3- 1) emotional 2) experienced 3) conscious 4) terrible

Thanks in advance.
