Problem Group 1 Title
This is the statement for problem group one. You can add a link to websites like this: http://www.google.com. You can add images like this:
The image source can either be a local path, or some web URL. Images can be embedded anywhere: within problem groups, problems or options. It also supports syntax highlighting like this: 
int a = 2;
int b = 3;
System.out.println(a + b);
Quizgen supports LaTeX: \[ a = \begin{pmatrix} 1 \\ 3 \\ 2 \end{pmatrix} , \quad b = \begin{pmatrix} 2 \\ 6 \\ 4 \end{pmatrix} , \quad c = \begin{pmatrix} 1 \\ 3 \\ 0 \end{pmatrix} . \] A blank line marks the end of this problem group introduction text and the beginning of the first problem.
This is the first problem in the problem group with some LaTeX: $a_3$.
  1. This is an option.
    Incorrect. You can add an explanation for an option after the double colon to explain why it is correct/incorrect.
  2. This is another option. Observe that explanations are optional.
    Incorrect.
  3. This option is the correct option since it is marked with an equal to sign.
    Correct!
Again, a blank line marks the end of the options. Here's another problem in this problem group with more inline latex $c$ and $d$. Quizgen supports displayed equations as well: \[ x=Zy + a - c. \]
  1. Yes.
    Incorrect.
  2. No.
    Correct!
You can also have problems with multiple correct responses. Students will be asked to select all that apply, and then submit their responses.

This problem group has no title and has no introduction. When the text following the start of a new problem group is immediately followed by the options, it is inferred to be a problem.
  1. Yes I understand.
    Correct! Great! Here's some latex $\|a + b + c\|.$
  2. No.
    Incorrect. Please email me and I'll try to help!
This is another problem in this problem group.
  1. This is a great tutorial!
    Incorrect.
  2. This tutorial can be improved. I'm going to email you with suggestions so you can do a better job.
    Correct!
