The steel industry has changed radically over the last two decades, as large, integrated
companies such as Bethlehem Steel once conducted operations from mining at one
end of the process to shipping at the other have greatly downsized, or in some cases
shut down altogether.
A. as large, integrated companies such as Bethlehem Steel
B. as large, integrated companies, such as Bethlehem Steel, that
C. with large, integrated companies, such as Bethlehem Steel, that
D. while large, integrated companies, such as Bethlehem Steel, that
E. and large, integrated companies such as Bethlehem Steel
Here the usage of that is necessary. Let us consider choice A to understand this better. Choice A has three clauses.
Clauses:
1.The steel industry has changed radically over the last two decades,
2. as large, integrated companies such as Bethlehem Steel once conducted operations from mining at one
end of the process to shipping at the other
3.have greatly downsized, or in some cases shut down altogether.
Here, integrated companies is the subject and "conducted" as well "have downsized" are the verbs. However, if you observe closely, you would see that there is no subject for "have greatly downsized". To assign it a subject we need to ensure that the first part of the sentence should be connected by "that".
Hope this helps!
