All quiz answers should be quite short (no setup or output, many assumptions)

1. In IE with JavaScript get an xml object (as sent from the server) from an iframe
2. Dynamically call a java Class and method from within java
3. List the values of a column that have a 2nd column who's value is not in any other row with SQL
4. From a POISX CLI in one line individually compress all iso files in all sub directories using no loops and with the date inserted into the filenames
5. Output a Git histoy from the beginning of the year in the format "graph tab date tab message"

For each question:

1 point for doing something logical
1 point for understanding/answering the question asked
1 point for getting a working answer
1 bonus point for being concise or explaining why the question/answer is useful
