"i see a vacant seat," replied the ghost, "in the poor chimney corner, and a crutch without an owner, carefully preserved." what do these lines mean?

dr. kings dream speech

explanation:

it was late in the day and hot, and after a long march and an afternoon of speeches about federal legislation, unemployment and racial and social justice, the rev. dr. martin luther king jr. finally stepped to the lectern, in front of the lincoln memorial, to address the crowd of 250,000 gathered on the national mall.

faulty parallelism is a construction in which two or more parts of a sentence are equivalent in meaning but not grammatically similar in form.

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

the hikers knew that the hike was six miles, that it usually required the entire day, and it would not be wise to start after 10: 00 a.m.

the problem is the last sentence, the first two have 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 all three sentences:

the hikers knew that the hike was six miles, that it usually required the entire day, and it would not be wise to start after 10: 00 a.m.

Those line mean that if Scrooge doesn't help the Cratchit family, the boy will probably die. Tiny Tim has to walk using crutches because he is suffering from a terrible disease (probably polio) and the Ghost says that if he doesn't get the medical help he needs, he will probably die and leave 'a crutch without an owner.'
