Was forward this test by a friend restoring Lucky Thirteen in North Carolina.

Some answers may be incorrect. He would be most grateful for the correct answers from the vast knowledge and experience of members here. 

So far have noticed these:

Q24 - the answer should be (b) NOT (a)
Q51 - the answer should be two NOT three


Thank you and many kind regards.
