Answer 1

Assuming that you have the right compiler version (use a different one if needed) you are missing a few keywords from the function: public to denote that the function is accessible everywhere and memory to denote that the string is loaded from memory - string parameters have to be loaded from memory.

So the corrected version is:

function test() public pure returns (string memory) {
    return "HelloWorld";
}
