Directions: Passage For Question 1 to 9
Paleontologists have been intrigued by the fossil remains of the pterosaurs, the first flying vertebrates, for over two centuries. The challenges of powered flight and the true nature of these creatures, whether they were reptiles or birds, have been subjects of debate among scientists. However, it is generally accepted that pterosaurs were reptiles based on their skull, pelvis, and hind feet anatomy. Their wings, characterized by a greatly elongated fourth finger supporting a wing-like membrane, suggest they did not evolve into birds. Pterosaurs had a combination of bird-like and bat-like features in their overall structure and proportions, which is not surprising considering the aerodynamic constraints of flight in vertebrates.
Both pterosaurs and birds have hollow bones, reducing weight, but bird bones are reinforced internally. It is likely that pterosaurs had a coat of hair to insulate against heat loss and streamline their bodies during flight. The recent discovery of a pterosaur specimen covered in hair-like fossil material supports this hypothesis. The question of how pterosaurs became airborne has led to various suggestions, including launching themselves from cliffs, dropping from trees, or using updrafts from high waves. Each hypothesis has its limitations, such as the mismatch between pterosaur feet and bat feet for cliff launching and the potential difficulty of large pterosaurs landing in trees without damaging their wings.

Q. The author uses "labor market problems' in lines 1-2 to refer to which of the following ?
Directions: Passage For Question 10 to 15
The extent of suffering caused by labor market problems is a critical but contentious social policy question. Social statistics often exaggerate the level of hardship experienced. Unemployment today does not have the same severe consequences as in the 1930s when most jobless individuals were primary breadwinners, income levels were closer to subsistence, and social programs were lacking. Factors such as increased affluence, more dual-earner families, and improved social welfare have mitigated the impact of joblessness. Similarly, earnings and income data overstate hardship. Many individuals with low hourly earnings, including those near the minimum wage, come from relatively affluent families with multiple earners. Poverty statistics also do not accurately reflect labor market issues, as they mainly include the elderly, disabled, or individuals with family responsibilities who are not part of the labor force. However, social statistics also underestimate the hardship related to the labor market. Unemployment counts exclude fully employed workers with low wages, who still live in poverty. Low wages and repeated or prolonged unemployment often combine to undermine self-support. Additionally, the number of people experiencing joblessness at some point during the year is higher than the average monthly unemployment, with part-time workers and individuals wanting a job but not in the labor force. Furthermore, income transfers primarily focus on the elderly and dependent, neglecting the needs of the working poor. The contradictory evidence makes it uncertain whether the number of individuals suffering due to labor market problems is in the hundreds of thousands or tens of millions, and whether high levels of joblessness require job creation and economic stimulus. The existing poverty, employment, and earnings statistics are inadequate for measuring the consequences of labor market problems.
