Answer:
To remove the "dead-weight phrase" in the sentence: "It has been found that most people consider buying a house the largest purchase they can ever make," it can be rewritten as follows:
"Most people consider buying a house the largest purchase they can ever make."
Step-by-step explanation:
A dead-weight phrase is one that is not helpful in a sentence to convey the intended meaning. This implies that the meaning can still be picked up without the phrase. For example, the phrase: "it has been found that" is not necessary in the sentence. The meaning of the sentence is conveniently conveyed with its omission. The meaning is not lost if the sentence is rewritten as "Most people consider buying a house the largest purchase they can ever make."
Generally, a dead-weight is an unnecessary burden that can be jettisoned to make a load lighter. Also an unhelpful person can be considered as a dead-weight.
