Per fornire la funzionalità delle domande vero/falso, abbiamo bisogno di un insieme di input che non consentano di selezionare entrambe le opzioni contemporaneamente.

All'interno di ogni elemento della lista, annida un elemento label e all'interno di ogni elemento label annida un elemento input con il type appropriato.

--hints--

Dovresti annidare un elemento label all'interno del primo elemento li.

assert.exists(document.querySelectorAll('ul.answers-list > li')?.[0]?.querySelector('label'));

Dovresti annidare un elemento label all'interno del secondo elemento li.

assert.exists(document.querySelectorAll('ul.answers-list > li')?.[1]?.querySelector('label'));

Dovresti annidare un elemento label all'interno del terzo elemento li.

assert.exists(document.querySelectorAll('ul.answers-list > li')?.[2]?.querySelector('label'));

Dovresti annidare un elemento label all'interno del quarto elemento li.

assert.exists(document.querySelectorAll('ul.answers-list > li')?.[3]?.querySelector('label'));

Dovresti annidare un elemento input all'interno del primo elemento label.

assert.exists(document.querySelectorAll('ul.answers-list > li')?.[0]?.querySelector('label')?.querySelector('input'));

Dovresti annidare un elemento input all'interno del secondo elemento label.

assert.exists(document.querySelectorAll('ul.answers-list > li')?.[1]?.querySelector('label')?.querySelector('input'));

Dovresti annidare un elemento input all'interno del terzo elemento label.

assert.exists(document.querySelectorAll('ul.answers-list > li')?.[2]?.querySelector('label')?.querySelector('input'));

Dovresti annidare un elemento input all'interno del quarto elemento label.

assert.exists(document.querySelectorAll('ul.answers-list > li')?.[3]?.querySelector('label')?.querySelector('input'));

Dovresti dare al primo input un type del valore radio.

assert.equal(document.querySelectorAll('ul.answers-list > li > label > input')?.[0]?.type, 'radio');

Dovresti dare al secondo input un type del valore radio.

assert.equal(document.querySelectorAll('ul.answers-list > li > label > input')?.[1]?.type, 'radio');

Dovresti dare al terzo input un type del valore radio.

assert.equal(document.querySelectorAll('ul.answers-list > li > label > input')?.[2]?.type, 'radio');

Dovresti dare al quarto input un type del valore radio.

assert.equal(document.querySelectorAll('ul.answers-list > li > label > input')?.[3]?.type, 'radio');
