A.
Creating a fundamental shift in American foreign policy and
establishing a "policy of containment" that framed our foreign policy as a battle between the forces of good (America and other democratic societies) and evil (the Soviet Union and other communist nations),
was the 1947 Truman Doctrine.
- wrong!
using verb-ing phrases to describe actions done in the past is wrong and the sentence uses passive voice.
B. The 1947 Truman Doctrine created a fundamental shift in American foreign policy, establishing a "policy of containment" that framed our foreign policy as a battle between the forces of good (America and other democratic societies) and evil (the Soviet Union and other communist nations).-
Correct!- the sentence is the most concise and is in active voice!
C. Creating a fundamental shift in American foreign policy
was the Truman Doctrine,
which was put forth in 1947, and
which established a "policy of containment" that framed our foreign policy as a battle between the forces of good (America, along with other democratic societies) and the forces of evil (the Soviet Union, along
with other communist nations).
The option has many passive elements and is redundant--- there also seems to be a parallelism error
D. The 1947 Truman Doctrine created a fundamental shift in American foreign policy, establishing a "policy of containment" that framed our foreign policy as a battle between American and other democratic societies, which
it considered the forces of good, and the Soviet Union and other communist nations,
which it considered the forces of evil.
which illogically modifies communist nations.
and it is ambiguous and is unnecessary
E. A fundamental shift in American foreign policy was created in 1947 by the Truman Doctrine, which importantly established a "policy of containment," a policy that framed our foreign policy in terms of a battle between good and evil, with the good forces
being America and other democracies and the evil forces
beingthe sentence is awkward and lacks a proper meaning!
