There should be fixed and sample tests like below:

• Michael Michael. (only 1 valid last name same as first name, still fits in scope since description does not mention otherwise)

• Michael Burmor Michael Jordan Michael Justin Michael Jackson Michael Phisher (a sentence consisting of only all valid names)

It wasn't very clear how to get the current year from the description. Maybe this could be explained?

JS: Node v12 should be used enabled along with its appropiate assertion tools (Mocha + Chai).

JS: No random tests

I think it's better to specify the exact age range of teens in the description. It can mean differently from one place to another.

Cambridge Dictionary defines "Teens" as individuals in the 13-19 years age group.
https://dictionary.cambridge.org/dictionary/english/teens

WHO defines 'Adolescents' as individuals in the 10-19 years age group
https://www.who.int/southeastasia/health-topics/adolescent-health

Some might argue that adolscents is different to teens, but some other might argue otherwise. In the end, it's ambigious.

Ruby 3.0 should be enabled, read this to learn how to do it

Please organize the structure of test fixture as following (although it has been mentioned in the attached link, I'm repeated here again)

describe "<This message should describe the categories of test groups inside this block>" do
  it "<A short message describing this test group>" do
    expect(...).to eq(...) #Assertions
    #Or Test.assert_equals(user_response, reference_response)
  end
end
