Question

Which sentence should be revised for clarity?

In the years following World War I, there was a great deal of anti-immigrant sentiment in the United States.
As a result, the US government enacted various laws that restricted immigration.
The Immigration Act of 1924 established a quota system.
This law stated that no more than two percent of the population of each nationality living in the United States could be admitted as immigrants.
Eliminating immigration from Asia, it also limited immigration from Europe, Russia and Italy in particular.

Answer 1

The very last sentence "Eliminating immigration from Asia, it also limited immigration from Europe, Russia, and Italy in particular"

Answer 2

Eliminating immigration from Asia, it also limited immigration from Europe, Russia and Italy in particular.

Step-by-step explanation:

The sentence chosen wrongly separates the subject from the predicate with a comma and introduces the pronoun it when it is not unnecessary. The reason for that is that the sentence already contains a subject: Eliminating immigration from Asia. As a result, the use of the pronoun it immediately after the subject is not required. Thus, the correct version of the sentence is the following:

Eliminating immigration from Asia also limited immigration from Europe, Russia and Italy in particular.
