I'm with you!

One has to marvel at the lack of proofreading behind:

What is the simplest type of data that Perl can work with?

   1. element
   2. scalar
   3. vector
   4. component

and then (in the answer section):

The simplest type of data that Perl can work with is called a scalar. 
+Answer: C.

There wasn't any answer "C" ...?!  Oh, we're supposed to do a mental translation from numbers to letters!

There's also a typo, in question #9:

Which of the following commands should be used to open a filehandle na
+med
KAREN to an existing file named sw?

   1. open KAREN ">sw";
   2. open KAREN, ">sw";
   3. open "sw" KAREN;
   4. open ">sw", KAREN;

I didn't like any of them ... the only one that works (#2) overwrites the file "sw", whereas the question implies that the file is being opened for read access.

As does the answer (which doesn't match):

The command open KAREN, "sw"; should be used to open a filehandle name
+d KAREN
to an existing file named sw. Answer: B.

I've only read the first 16 of them, but it's not a test I'd be likely to use in an interview session.

Oh, and one final nit:  I always think of arrays as going horizontally from left to right, but if they are vertical, then wouldn't:

Which operator can be used to take the bottom item from an array?

   1. pop
   2. push
   3. pull
   4. plant

Have it upside-down?  If anything, push and pop should work with the top of the array, I'd think...
