[BrandenF768]

Sentence Correction

The single-family house constructed by the Yana, a Native American people who lived in what is now northern California, was conical in shape, its framework of poles overlaid with slabs of bark, either cedar or pine, and banked with dirt to a height of three to four feet.

A) banked with dirt to a height of
B) banked with dirt as high as that of
C) banked them with dirt to a height of
D) was banked with dirt as high as
E) was banked with dirt as high as that of

[End of question]

Clearly A) is correct. However, I wanted to confirm my understanding of the proper usage of "to a height of" vs. "as high as". My current understanding tells me that "as high as" is a COMPARISON, so that the phrase must be followed by an object to which you are making the comparison. However, "to a height of" must be followed by an explicit unit of measurement and associated magnitude (eg. three to four feet). If "three to four feet" were placed after "as high as", that would be nonsensical, as the object is not as high as 3 or 4 feet--it IS 3 to 4 feet.

Please confirm.
