Incorrect English grammar. She sings more slowly than I.

[janerums17]

Not correct usage of grammar. 'than I'.

[MaryLM514]

"She sings slower than I" - was marked incorrect! That is the correct form in English. Ugh. Ruined my perfect score.

[VZbLAexr]

To be fair though, it should be "more slowly".

[Ellen147987]

COME ONE DUO!! IT HAS BEEN A YEAR - SHE SINGS SLOWER THAN I IS CORRECT!!!

[VZbLAexr]

There used to a running joke. When people spoke with bad grammar, someone would say, "Speak proper!" The joke being that it should be, "Speak properly!"
There is no such adverb as slower, that's an adjective.
She sings more slowly. ...
Then there's the 'me' vs. 'I' issue which, IMO, is dated - not many people would actually say 'I'. Plenty of people still say, "more slowly."
