The request object stores route parameters in the parameters object. This should be true when I type req.params

If the distinction being made here is between "params" and "parameters" it is my opinion that questions such as this which focus on semantic nuances serve only to confuse rather than teach.

I understand that as coders we have to be able to spot these niggling differences in our code. But if that is the nature of the question, then the question itself, within the context of the quiz, should change the font or style of the word "parameters" in order to signify a specific reference to actual code.

If the creators of the course and the quiz disagree, then someone should have taken the time to explain the answer when the wrong answer is given, as I have seen in some treehouse quizzes.

I got this one wrong myself when I took this course and the conclusion I came to was that the answer is false because the question says the parameters object when it is technically the params object.

Same here. It should be bold or emphasized somehow
