Step 7: When the next button is clicked, show another trivia
question in the question paragraph, clear the text box, enable the text box and
submit button, clear the result paragraph, and hide the next button.
Hint: Your next function should have something like:
questionParagraph.innerHTML = `some question`
answer.value = ``
answer.disabled = false
submitButton.disabled = false
resultParagraph.innerHTML = ``
nextButton.style.display = `none`
