Which three sentences correctly use parallel structure?
When things go wrong, Carl tends to brood for hours and to blame others.

After watching some TV, I was talking to my daughter and read e-mail.

The school was closed not only because of the snow and ice but also because of the lack of heat.

The ice was a greater problem for the electrical power company than for the natural gas company.

in this particular instance I would try to identify the 1 sentence that does *not* use parallel structure

as a hint, it has inconsistent verb forms (for example, if you want to use the verb "running" you must keep using the progressive -ing form, so you would say "I like running and swimming" rather than "I like running and to swim"

with that being said, which sentence in your problem do you think has the same verb problem?
