interested!

@dustinbodnar12278 Literally laughing so hard rn. This made my day.

me too! could it be because of the change in the courses? #help

I just understand power as being a relational phenomenon e.g., Neptune and Pluto both have a powerful gravitational pull but as we've learned, not powerful enough to pull Uranus away. Only if we know whether a gravitational pull is powerful enough to potentially be the source of tugging, should it become relevant to the support used for the argument, and weaken it - no? When do you know that it is okay to take powerful as meaning powerful enough and when not to? In this case, I understand why comets being present addresses the flaw (and your explanation really helped) but in the future, what if terms like this are thrown in and precisely used to make the answer choice incorrect?

Could someone please explain why we are able to interpret "powerful" as meaning one that is strong enough to render it as an alternative cause to the detected tugging of Uranus, and thus weaken the argument? I felt that powerful is a term that could be questioned because we don't know what the comets are powerful in relation to..
