Hi all,
It seems like we have two different questions getting merged under the same thread :
1)Knowledge of the winter behaviour of emperor penguins has been gained slowly because of high winds, temperatures around minus 60 degrees Fahrenheit,
the fact of round-the-clock darkness and frequently sudden blizzards make the Antarctic habitats of the emperors dangerous places for humans in winter.
A. the fact of round-the-clock darkness and frequently sudden blizzards make
B. round-the-clock darkness, with frequently sudden blizzards, make
C. round-the-clock darkness, and frequent sudden blizzards make
D. the fact of round-the-clock darkness, with frequent sudden blizzards, making
E. round-the-clock darkness, and frequent sudden blizzards making
I will go with E for this version. "Because of" requires noun,thus the use of "make" is not appropriate.
Option D is out because we have several items that make studying the emperor penguin hard.
Just one question,"making" modifies only the last item of the list or the whole list?
I guess it is for only the last item.Comma is required to modifies the whole list.2)Knowledge of the winter behaviour of emperor penguins has been gained slowly because of
high winds, temperatures around minus 60 degrees Fahrenheit, the fact of round-the-clock darkness and frequently sudden blizzards make the Antarctic habitats of the emperors dangerous places for humans in winter.
A. of high winds, temperatures around minus 60 degrees Fahrenheit, the fact of round-the-clock darkness and frequently sudden blizzards make
B. of high winds, temperatures around minus 60 degrees Fahrenheit, round-the-clock darkness, with frequently sudden blizzards, make
C. high winds, temperatures around minus 60 degrees Fahrenheit, round-the-clock darkness, and frequent sudden blizzards make
D. high winds, temperatures around minus 60 degrees Fahrenheit, the fact of round-the-clock darkness, with frequent sudden blizzards, making
E. high winds, temperatures around minus 60 degrees Fahrenheit, round-the-clock darkness, and frequent sudden blizzards making
Presuming the underlined portion cover "of",I will go with C for this version.Option A and B are out since "because of" require noun.The use of "make" is inappropriate.Option D and E are out since "because" requires clause.
