What can a reader infer based on the information in the
excerpt?
The wind was fierce, often blowing the sled over and
keeping the dogs at a slow trot. Togo went steadily on.
The storm had swept much of the snow off the trail and
exposed the glare ice below. The dogs frequently
slipped and skidded sideways, endangering Seppala's
grasp on the sled. The light began to fade. As night
approached, it was only Togo's remarkable sense of
direction and Seppala's determination that brought
them across the bay and back onto the original trail.
Seppala's dog Togo was not used to pulling a sled
during a fierce storm.
Seppala almost gave up on trying to keep his dogs
moving during the night.
Seppala and his dog Togo were too cautious on the
trail and lost time.
Seppala and his dog Togo were extremely
courageous and strong-willed.

faulty parallelism is a grammar construction where there is no balance in the parts of a sentence they have a similar meaning but the grammar structure is not equivalent.

the correct version of this faulty parallelism in the sentence is:

jefferson wrote the declaration of independence, and he was the nation's third president.

the problem with the first version is that the sentence:

"jefferson was both the writer of the declaration of independence"

presents jefferson as both a subject and an agent for the verb "write" because if he was "the writer" then the declaration of independence was written by him, besides that fact, the sentence presents a dependent clause.

while the second sentence:

he was the nation's third president.

presents a basic subject+verb+object structure

so, to give a proper balance to the structure, or better said, to give a parallel structure, we must write a basic s+v+o structure in both sentences:

jefferson wrote the declaration of independence, and he was the nation third president.

the answer should be b.

explanation:

it should be b because she researched before writing so it would be in past tense. "the author researches her subject before she had written the first draft.

don't enter the room

explanation:

or you can just ask him to move away from his house

the sentence that avoid faulty coordination is:

culture, which is well represented in philadelphia, plays a major role including theatre, music, and the visual arts.  

faulty coordination occurs when the writer gives equal importance two different ideas (clauses) which in fact are not equivalent. in order to correct a misplaced clause or idea, the writer can place less important or emphatic ideas in a relative clause as in the previous sentence.
