a. lack of evidence

c. irrelevant claim

d. false assumption

f. bad inference

Explanation:

the lack of evidence, an irrelevant claim, a false assumption, and a bad inference are all signs of a weak argument.

a grammatical error doesn't necessarily show that someone has a bad argument, as someone could still have a good argument even with grammatical errors.

a surprising observation also isn't a sign of a weak argument.
