Which of the following corrects the error in meaning and usage in the sentence below? the building design lacks a proportion façade. the column width and the front wall are not well-balanced. change design to designate. change lack to lacking. change proportion to proportional. change width to wideness.

The answer is: Change proportion to proportional.  

The noun proportion is a part, share or number in comparison to a whole. The adjective proportional, on the other hand, means corresponding in size or amount.

In this case, the adjective proportional modifies the following noun façade, which is the front face of a building.

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.
