Q.1. Studying the fluctuations in global precipitation is crucial in comprehending the impact of climate change on the water cycle and global energy. Satellite meteorology utilizes both infrared and microwave data to estimate rainfall rates. The infrared method offers a spatial resolution of 4 km and a temporal resolution of 30 minutes, while ground-based radar measurements are used to establish a loose correlation between cloud-top properties, such as temperature and texture, and surface precipitation. On the other hand, microwave data, although less readily accessible, interacts directly with the actual precipitating particles within the potential rain clouds, which are opaque at other frequencies.

Place 'Yes' if the conclusion does follow. Place 'No' if the conclusion does not follow.

(a) When examining the formation of rain droplets, microwave radiation proves to be more precise than infrared radiation.
(b) Microwave radiations can penetrate through precipitating clouds due to their transparency.
(c) In comparison to microwave data, infrared data offers a broader spatial coverage.
(d) The microwave method provides precipitation data with a frequency of at least 50 times per day.
(e) Similar to infrared and microwave satellites, weather radars are positioned in space.

Yes, the conclusion follows. The passage mentions that microwave data interacts directly with the actual precipitating particles within rain clouds, indicating its precision in studying the formation of rain droplets compared to infrared radiation.

Yes, the conclusion follows. The passage states that microwave radiations can penetrate through precipitating clouds due to their transparency, implying that they are capable of passing through these clouds.

No, the conclusion does not follow. The passage does not provide information comparing the spatial coverage of infrared and microwave data.

No, the conclusion does not follow. The passage does not specify the frequency at which the microwave method provides precipitation data.

No, the conclusion does not follow. The passage does not mention the positioning of weather radars in space; it only discusses the use of ground-based radar measurements in combination with satellite meteorology.

Q.2. Researchers conducted a study to determine the effectiveness of a new drug in reducing cholesterol levels. The study involved 500 participants who were randomly assigned to two groups: Group A received the new drug, while Group B received a placebo.

Q.10. Due to the construction of hydroelectric dams, various areas that were previously accessible have been blocked off, resulting in the separation of salmon from their spawning grounds. The remaining accessible waters have experienced a reduction in their carrying capacity due to factors such as warmer temperatures, chemical pollutants, and the introduction of non-native species and hatchery-reared fish over time. The release of hatchery fish, intended to supplement the declining wild population, may introduce contagious diseases. The abundance of juvenile salmon at different life stages, excluding the smolt stage that migrates to saltwater and returns to its native rivers for reproduction, is inversely related to the existing population density.

Place 'Yes' if the conclusion does follow. Place 'No' if the conclusion does not follow.

(a) The typical spawning grounds for salmon are located in the oceans.
(b) Juvenile fish from hatcheries reach their designated release points when they have matured into young adults.
(c) The native salmon population is adversely affected by the salmon farming industry.
(d) In rivers designated for hydropower projects, hatchery-reared juveniles of a relatively young age are released.
(e) Increasing the water's carrying capacity proves to be a more effective method for restoring the salmon population than introducing hatchery-reared fish.

(a) No. The statement does not provide any information about the typical spawning grounds for salmon. It only mentions that the construction of hydroelectric dams has blocked off access to spawning grounds, but it does not specify their location.
(b) No. The statement does not provide information about the maturity or release points of juvenile fish from hatcheries. It only mentions that the release of hatchery fish may introduce contagious diseases.

(c) No. The statement does not directly address the impact of the salmon farming industry on the native salmon population. It focuses on the adverse effects of factors like hydroelectric dams, warmer temperatures, chemical pollutants, and the introduction of non-native species and hatchery-reared fish.

(d) Yes. The statement explicitly mentions that hatchery-reared juveniles are released in rivers designated for hydropower projects.

(e) Yes. The statement suggests that the reduction in carrying capacity of accessible waters, combined with other factors like warmer temperatures, chemical pollutants, and the introduction of non-native species and hatchery-reared fish, has negatively affected the salmon population. Therefore, increasing the water's carrying capacity could be a more effective method for restoring the salmon population than relying solely on introducing hatchery-reared fish.
