There are already open issues about the same, please don't open another.

This kata is not correct. The question mentions something and the sample tests are something different. Please check and rewrite this kata.

Ruby 3.0 should be enabled.

The question and description should be fixed or the tests should be fixed.

Duplicate issue.

The question is wrong

The question says to check for second vowels when in reality it is just asking for the total number of vowels. The question and description should be fixed OR the tests should be fixed

Already mentioned below by kangacoyote and still an open issue, closing this one.

Your expected results do not match with what is correct: For example,

"my first kata" 3 should be 1 (only 'kata' has two vowels)

"Once upon a time" 7 should be 3 (once, upon, time)

Up on melancholy hill"6 should be 2 (melancholy, hill)

"There's a plastic tree"7) should be 3 (There's, plastic, tree)

"bbb ee e"3) should be 1 (ee)

"Aaa a"4) should be 1 (Aaa)

Duplicate issue. See kangacoyote's post below.

I loved that i could use 3 nested loops, but the examples could be better.

The author changed the kata at some point and translations (Python was one of them) were left as they were.

I may be (probably am) missing something, but this description (and the example given with it) asks users to count the number of words that have more than one vowel in the given string. The actual tests (and therefore the solution) look for the total number of vowels in the string. These are two very different problems. Again, it's possible I just didn't understand the instructions, but if that's the case then perhaps they should be made more clear.
