Over the past two years, the population of the Rugian Republic, which is closely linked to the size of its labor force, has declined from 117.6 million to 115.4 million, while the country’s GDP has remained stable. A country’s GDP is determined by two main factors: the size of its labor force and the productivity of its workers. Therefore, if the population decline in the Rugian Republic continues, the country’s GDP will soon decrease.
Which of the following, if true, most strengthens the argument?
A. No significant technological advancements are expected to increase the productivity of the labor force.
B. Automation has enabled manufacturing companies in the Rugian Republic to increase their output.
C. The Rugian Republic’s economy is shifting from goods production to services, which typically generate higher productivity per worker.
D. Immigration to the Rugian Republic has been increasing and is expected to continue growing.
E. A growing number of young people are entering the workforce, while older workers are delaying retirement longer than before.

Official Solution:

A country’s GDP is determined by two main factors: the size of its labor force and the productivity of its workers. Therefore, if the population decline in the Rugian Republic continues, the country’s GDP will soon decrease.

A. No significant technological advancements are expected to increase the productivity of the labor force.
B. Automation has enabled manufacturing companies in the Rugian Republic to increase their output.

D. Immigration to the Rugian Republic has been increasing and is expected to continue growing.
E. A growing number of young people are entering the workforce, while older workers are delaying retirement longer than before.
(A) Correct. The passage states that GDP is determine by size of the labor force and productivity of the labor force. The passage states that the size of the labor force has decreased. If productivity remains the same because there are no technological advances expected, the GDP will decline.
(B) This answer choice suggests that productivity has increased; this could offset the decrease in the labor force and weaken the argument.
(C) This answer choice suggests that productivity will increase; this could offset the decrease in the labor force and weaken the argument.
(D) If level of legal immigration to the Rugian Republic keeps increasing, then the declining population trend should reverse, and GDP should go up as the labor force increases, thus weakening the argument.
(E) This answer choices suggests that the size of the labor force will increase, which may offset the population decline and thus weakens the argument.

bb, the passage gives information that the population declined, but in the explanation of the correct answer choice A and other choices, you say that "the size of the labor force has decreased.", which requires additional assumption, that "population decline = labour force decline".
