OK ... what have you tried until now, what happens and what should not happen ?
Which part of the code you don't understand ?

Richard MacCutchan 11-Oct-17 9:31am

You really need to go back to basics and learn how to use lists and loops.

Read the question carefully.
Understand that English isn't everyone's first language so be lenient of bad spelling and grammar.
If a question is poorly phrased then either ask for clarification, ignore it, or edit the question and fix the problem. Insults are not welcome.
Don't tell someone to read the manual. Chances are they have and don't get it. Provide an answer or move on to the next question.

We don't know what it is supposed to do, what it does that you didn't expect, or didn't do that you did. We don't know what you entered in order to get it to do that!

So, its going to be up to you.
Put a breakpoint on the first line in the function, and run your code through the debugger. Then look at your code, and at your data and work out what should happen manually. Then single step each line checking that what you expected to happen is exactly what did. When it isn't, that's when you have a problem, and you can back-track (or run it again and look more closely) to find out why.

Sorry, but we can't do that for you - time for you to learn a new (and very, very useful) skill: debugging!

it does not work!

You only forgot to tell us what your code is supposed to do and how it go wrong.

Use the debugger to see what your code is doing, it should help you to understand what is wrong.

By the way:
- in Q1 Ireland have 2 official languages, Irish and English.
- in Q6 if 90-110 is the correct answer, 80-120 should also be correct since it include the previous one.
- in Q10, 'Agreable' is not French, but 'Agréable' is.
- in Q12 and following, I fear 'Bernadette Moore' is not the answer of those questions.

There is a tool that allow you to see what your code is doing, its name is debugger. It is also a great learning tool because it show you reality and you can see which expectation match reality.
When you don't understand what your code is doing or why it does what it does, the answer is debugger.
Use the debugger to see what your code is doing. Just set a breakpoint and see your code performing, the debugger allow you to execute lines 1 by 1 and to inspect variables as it execute.

Debugger - Wikipedia, the free encyclopedia[^]
http://docs.oracle.com/javase/7/docs/technotes/tools/windows/jdb.html[^]
https://www.jetbrains.com/idea/help/debugging-your-first-java-application.html[^]
The debugger is here to show you what your code is doing and your task is to compare with what it should do.
There is no magic in the debugger, it don't find bugs, it just help you to. When the code don't do what is expected, you are close to a bug.
