Flat tire<br>Allie was driving back home. But her tire was flat. She had to call for help. Someone brought a pump. Then she was on her way home.
Allie had to call a service who brought a pump
It is not stated who Allie called. I think the system got it wrong because the statement can be inferred to be correct but there are no supporting details
( z1 obligate :ARG2 ( z2 call :ARG0 ( z3 person :name ( z4 name :op "Allie" ) ) :ARG1 ( z5 service :ARG0-of ( z6 bring :ARG1 ( z7 pump ) ) ) ) )
