idk but I ASSUME (lol) assumptions are EXCUSES.. or at least for me, I put it in place of the word assumption. the more EXCUSES (assumptions) in the argument, the faultier and less valid/unsupported the conclusion. With less EXCUSES the statement becomes most likely to be true and is valid or can be supported and seen as a strong argument .... am I correct?

less excuses: more believable

more excuses: less believable

ok I have an example argument trying to see if im getting this:

So I take a test

if I get an A: there is valid reason to conclude I studied for the test

if I get an F: its unreasonable/unsupported to conclude I studied as my grade reflects

but if I get a B or C: depending on points(how strong the reason is); shows how and where on the frame the grade would reflect the conclusion

am I getting this right?
