With respect to Q 73 -

Ans is C, since phrase ' With no natural predators and expanses of green surban neighborhoods that allow no hunting' is a modifier of the noun deer population... it follows the rule that nouns should always be place immediately after or before the modifier.

73. With no natural predators and expanses of green suburban neighborhoods that allow no hunting, wildlife officials estimate the New Jersey deer population to have grown to exceed 175,000

A. With no natural predators and expanses of green suburban neighborhoods that allow no hunting, wildlife officials estimate the New Jersey deer population to have
B. With no natural predators and with expanses of green suburban neighborhoods that do not allow hunting, wildlife officials' estimate of the deer population in New Jersey has
C. With no natural predators and with expanses of green suburban neighborhoods where there is no hunting, the deer population in New Jersey, wildlife officials estimate, has
D. Without natural predators and no hunting allowed in expanse of green suburban neighborhoods, New Jersey has a deer population that wildlife officials estimate to have
E. Without natural predators and with expanses of green neighborhoods where there is no hunting, wildlife officials in New Jersey estimate a deer population that has

As per my understanding, With no natural predators modify the deer; and expanses of green suburban neighborhoods modify New Jersey.
How can this be possible?
thanks.
