E. When Bill Gates tested the windows operating system that was scheduled for a mass distribution campaign in the United States in 1995, he combined in it three big application packages.
A. From the construction it is not clear who was testing the Windows operating system. The part “combined in it by the operating system’s creator, Bill Gates, were three big application packages” should be constructed in active voice so as to make it clear that Bill gates was testing the system.
The use of the essential modifier “that was scheduled…” is wrong- A non-essential modifier is required because this modifier provides some additional information about the system. Use of essential modifier implies that there are many Windows operating systems, of which the one that was scheduled for a mass distribution is meant.
B. The sentence lacks the main verb. There are other verbs embedded within the modifiers, but there is no main verb for the sentence whatsoever.
The modifier starting with “combining” needs a subject of the clause which it is modifying. It should be “Bill Gates” who is actually doing the “combining ...”
C. The meaning is distorted - the intended meaning in the original sentence is that the combining occurred when testing was carried out. However this sentence omits the testing part altogether. It is not clear who combined the packages in the system.
D. The sentence lacks the main verb. There are other verbs embedded within the modifiers, but there is no main verb for the sentence whatsoever.
E. CORRECT. The basic structure of the sentence clarifies that When Bill Gates tested the system, he combined three big application packages in it. The modifiers, “the creator of Windows operating system” and “which was scheduled for a mass distribution campaign in the United States in 1995” clearly refer to “Bill Gates” and “the system” respectively.
