Sample Questions & Answers
Here are five challenging questions designed to test your understanding of Science and Technology topics relevant to competitive examinations:
Question 1:
Consider the following statements regarding the Artemis II mission:
1. Its primary objective is to land astronauts on the Moon’s surface, making it the first crewed lunar landing since Apollo 17.
2. The mission involves a crewed flyby around the Moon to test the Orion spacecraft’s systems with humans on board.
Which of the statements given above is/are correct?
(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) Neither 1 nor 2
Answer 1: (b) 2 only
*Explanation:* Artemis II is indeed a crewed flyby mission around the Moon, designed to test the Orion spacecraft and Space Launch System (SLS) with astronauts before any lunar landing attempts. The landing of astronauts on the Moon’s surface is planned for a subsequent mission, Artemis III, making statement 1 incorrect.
Question 2:
Which of the following medical imaging techniques primarily utilizes the principles of electromagnetic radiation *outside* the visible spectrum to create detailed images of internal body structures?
(a) Ultrasound
(b) Magnetic Resonance Imaging (MRI)
(c) Positron Emission Tomography (PET)
(d) X-ray imaging
Answer 2: (d) X-ray imaging
*Explanation:* X-ray imaging uses high-energy electromagnetic radiation (X-rays) to visualize bone structures and other dense tissues. Ultrasound uses sound waves, MRI uses strong magnetic fields and radio waves (which are part of the EM spectrum but often a distinct application in this context from X-rays), and PET uses radioactive tracers that emit positrons. While MRI uses radio waves, X-rays directly apply the principle of different absorption of electromagnetic radiation for imaging.
Question 3:
Recently, the term ‘CRISPR-Cas9’ has often appeared in news headlines. It is most accurately described as a:
(a) New type of artificial intelligence algorithm for predictive analytics.
(b) Gene-editing tool derived from a bacterial defense system.
(c) Revolutionary technology for developing quantum computers.
(d) Sustainable energy production method using advanced biofuels.
Answer 3: (b) Gene-editing tool derived from a bacterial defense system.
*Explanation:* CRISPR-Cas9 is a groundbreaking gene-editing technology that allows scientists to make precise changes to DNA. It was adapted from a natural defense mechanism found in bacteria and has immense potential in medicine, agriculture, and fundamental biological research.
Question 4:
With reference to Electric Vehicles (EVs), consider the following statements:
1. Lithium-ion batteries are currently the most common type of battery used in EVs due to their high energy density.
2. Regenerative braking systems in EVs convert kinetic energy back into electrical energy, thereby increasing efficiency.
3. The charging infrastructure for EVs primarily relies on direct current (DC) power transmission from the grid to the vehicle’s battery.
Which of the statements given above is/are correct?
(a) 1 and 2 only
(b) 2 and 3 only
(c) 1 and 3 only
(d) 1, 2 and 3
Answer 4: (a) 1 and 2 only
*Explanation:* Statements 1 and 2 are correct. Lithium-ion batteries are indeed dominant in EVs for their energy density, and regenerative braking is a key efficiency feature. However, statement 3 is incorrect. Most charging infrastructure for EVs uses alternating current (AC) power from the grid, which is then converted to DC by an on-board charger in the vehicle. Fast charging stations, however, can provide DC power directly.
Question 5:
What is the primary function of the Ozone Layer in Earth’s atmosphere?
(a) To regulate the Earth’s temperature and prevent global warming.
(b) To absorb harmful ultraviolet (UV) radiation from the Sun.
(c) To facilitate cloud formation and precipitation cycles.
(d) To reflect radio waves, enabling long-distance communication.
Answer 5: (b) To absorb harmful ultraviolet (UV) radiation from the Sun.
*Explanation:* The Ozone Layer, located primarily in the stratosphere, plays a critical role in absorbing most of the Sun’s harmful ultraviolet (UV-B and UV-C) radiation. This absorption protects life on Earth from the damaging effects of excessive UV exposure, such as skin cancer, cataracts, and damage to ecosystems.
