The correct answers are:
- The loss of skilled labor makes it hard for nations to improve
- Emigrants provide a needed skill set to their host countries.
Emigrants are the sector of a region's population that leaves that region to establish themselves somewhere else/abroad, generally aiming to find better working and living conditions there.
The human capital is a crucial asset for the economic activities in a region, as it comprises the skills and knowledge that its inhabitants have acquired through education and working experience. Potential and actual workers offer these skills in the labor markets.
Therefore, the loss of population decreases also the stock of human capital in the region and these losses related to such an important asset make it more difficult for the economy to grow. On the other hand, it increases the skill set, the human capital stock of their country of destination.
When emigrants settle somewhere, is because they have found a job position there and they are fulfilling the needs of an employer and an economic sector by providing their skills.

"Original Source Material
: We considered a number of methods for measuring similarity between countries with respect to their mathematics attainment. A simple comparison of scale scores over time was rejected as this would limit the investigation to asking how much respondents from a country know on a given topic. Instead, we chose an item-level analysis that allows for a closer examination of what respondents in a given country know and how this compares to other countries.

Student Version
: One criticism of using scale scores or total scores on a test is that it can hide interesting details. For example, Rutkowski and Rutkowski (2009, p. 140) rejected scale scores in favor of an item-level analysis since it would allow "for a closer examination of what respondents in a given country know and how this compares to other countries". References: Rutkowski, L., & Rutkowski, D. (2009). Trends in TIMSS responses over time: Evidence of global forces in education? Educational Research and Evaluation, 15(2), 137-152.
