Sentence Correction

The small but affluent nation of New
Malusidia (NM) faces a serious shortage of
manpower in the private sector. As a
result, about 30% of the workforce in NM is
comprised of foreign workers holding work
permits. Some of the foreign workers are
skilled; others are unskilled. To alleviate
the labor shortage, the government of NM
plans to offer permanent residence status
to any skilled work permit holder who has
resided in the country for longer than two
years.
To determine whether the plan is likely to
achieve its goal, it would be most useful to
know which of the following?
A) Whether the non-working dependents
of unskilled work permit holders are
permitted to reside in NM during the
work permit holder's term of
employment.
B) Whether NM requires that permanent
residents who intend to apply for
citizenship in NM renounce allegiance
to any other country in which they hold
citizenship.
C) Whether permanent residents of NM
are disqualified from applying for
certain jobs in the public sector.
D) Whether the government of NM plans
to introduce a new migration scheme
allowing skilled foreigners who have
never worked in NM to apply for
permanent residence.
E) Whether the average duration of
gainful employment in NM is greater
among foreigners who are permanent
residents than it is among foreigners
who hold skilled work permits.
