• Question 1 of 10 1. Question 1 points What is the demographic dividend? (a) The decrease in the total population of a country due to declining birth rates. (b) The economic growth potential resulting from a favorable age distribution within a population. (c) The increase in mortality rates among the elderly population. (d) The phenomenon where the dependency ratio exceeds the working-age population. Correct Ans: (b) Explanation: Context: The World Bank (as per “Jobs for Resilience, South Asia Development Update”) warned that South Asia, including India, is not utilizing its demographic dividend effectively. What is a Demographic Dividend? The demographic dividend refers to the economic growth potential that arises from changes in a population’s age structure. It occurs when the proportion of working-age individuals (15-64) in a population is larger than the dependent population (children and elderly), leading to increased productivity and economic growth. India is expected to enjoy this window for 37 years starting in 2018 and up to 2055 Refer: https://www.insightsonindia.com/2024/04/05/world-bank-warns-of-squandered-demographic-dividend/ Incorrect Ans: (b) Explanation: Context: The World Bank (as per “Jobs for Resilience, South Asia Development Update”) warned that South Asia, including India, is not utilizing its demographic dividend effectively.

• Question 3 of 10 3. Question 1 points When performing a genetic cross using a Punnett square, what do the letters inside the squares represent? (a) Phenotypic traits (b) Genotypic traits (c) Dominant alleles (d) Recessive alleles Correct Ans: (b) Explanation: Context: The Punnett square, named after British geneticist Reginald Punnett, is a grid used to predict the possible genetic outcomes of offspring when two individuals with known genotypes are crossed. It consists of a simple grid with squares representing possible combinations of traits inherited from each parent. This tool helps visualize the probabilities of different traits appearing in offspring and is commonly used in biology to understand inheritance patterns, such as dominant and recessive genes. Researchers utilize Punnett squares alongside Mendelian inheritance principles to study genetic traits in offspring, including those of animals and humans. The letters in the boxes of a punnet’s square represent a particular genotype, with each alphabet representing an allele, contrasting forms of a gene.

Named by the European Space Agency due to its association with the “kappa-Draconids” meteor shower, the comet exhibits a bright green colour due to the emission of emerald-coloured light from diatomic carbon molecules. Notable for its cryovolcanic nature, the comet regularly erupts, creating stunning displays of brightness. Comet tail glow predominantly consists of ionized gases that emit light when they interact with the solar wind. This process forms the characteristic tails of comets as they approach the Sun.

Explanation:

• S1: Registration of a trademark is not compulsory. However, the registration is the prima facie evidence of the proprietorship of the trademark under registration. While registration provides certain benefits, trademarks can still be valid and enforceable even if they are not registered. Common law trademarks can be established through consistent use in commerce.

• Question 8 of 10 8. Question 1 points Consider the following statements: The Commonwealth Games is held every five years, alternating between a summer and winter event. The inaugural Commonwealth Games were held in London, England in 1930. Participation in the Commonwealth Games is restricted to countries that were once part of the British Empire. How many of the above statements are correct about the Commonwealth Games? (a) Only One (b) Only two (c) All three (d) None Correct Ans: (a) Explanation: The Commonwealth Games is a quadrennial (occurring every 4 years) international multi-sport event involving athletes from the Commonwealth of Nations. It originated in 1930 (The 1st Commonwealth Games were held in 1930 at Hamilton, Canada) as the British Empire Games and evolved into its current format, embracing athletes with disabilities since 2002 and achieving gender equality in medal events in 2018. Hosted by various cities, Australia has held the Games the most times. The most recent Games were in Birmingham in 2022. India hosted the event in 2010 (in Delhi) The Commonwealth Games are open only to countries that were formerly part of the British Empire or territories that have a historical, constitutional, or geographical link to the Commonwealth.

• Question 9 of 10 9. Question 1 points What is the primary scale used to measure the magnitude of earthquakes? (a) Richter Scale (b) Fahrenheit Scale (c) Celsius Scale (d) Beaufort Scale Correct Ans: (a) Explanation: Context: A powerful earthquake of 7.2 magnitude struck Taiwan. What makes Taiwan and Japan so prone to earthquakes? Taiwan and Japan are highly prone to earthquakes due to their location along major tectonic plate boundaries. Both countries sit on the Pacific “Ring of Fire,” where several tectonic plates converge. Taiwan is situated on the boundary between the Philippine Sea Plate (PSP) and the Eurasian Plate (EP), while Japan is located at the juncture of the Pacific Plate (PP), Philippine Sea Plate (PSP), and Eurasian Plate(EP). The intense geological activity along these plate boundaries results in frequent seismic events, including earthquakes and volcanic eruptions. Additionally, both Taiwan and Japan have rugged terrain and mountainous regions, further exacerbating the impact of earthquakes. The Richter Scale, developed by Charles F. Richter in 1935, is a logarithmic scale used to measure the magnitude of earthquakes based on the amplitude of seismic waves.

• Question 10 of 10 10. Question 1 points Which of the following statements about the Ring of Fire is correct? (a) The Ring of Fire is a term used to describe a region of active volcanic and seismic activity encircling the Pacific Ocean. (b) The Ring of Fire is a man-made structure built to protect coastal areas from tsunamis and earthquakes. (c) The Ring of Fire refers to a fictional location in a popular fantasy novel series. (d) The Ring of Fire is a meteorological phenomenon observed in the Arctic region. Correct Ans: (a) Explanation: The Ring of Fire is a horseshoe-shaped region in the Pacific Ocean characterized by frequent seismic and volcanic activity. The Ring of Fire marks the convergence of several tectonic plates, including the Pacific Plate, and is associated with approximately 90% of the world’s earthquakes. The Ring of Fire hosts numerous volcanoes formed through subduction, where one tectonic plate is forced beneath another, leading to volcanic eruptions.
