• Question 1 of 5 1. Question Consider the following statements regarding Perform, Achieve, Trade (PAT) Scheme. Statement-I: The PAT Scheme targets industries to improve energy efficiency by setting specific goals. Statement-II: The PAT Scheme also allows trading surplus energy savings among industries. Which one of the following is correct in respect of the above statements? a) Both Statement-I and Statement-II are correct and Statement-II is the correct explanation for Statement-I b) Both Statement-I and Statement-II are correct and Statement-II is not the correct explanation for Statement-I c) Statement-I is correct but Statement-II is incorrect d) Statement-I is incorrect but Statement-II is correct Correct Solution: a) The Perform, Achieve, Trade (PAT) Scheme is a flagship initiative under the National Mission for Enhanced Energy Efficiency (NMEEE), targeting energy-intensive industries. Statement-I is correct because the PAT Scheme mandates specific energy efficiency targets for designated consumers (DCs) in sectors such as cement, power, and steel, aiming to reduce their energy consumption. Statement-II is also correct because the scheme incorporates a trading mechanism. Industries that exceed their targets generate Energy Saving Certificates (ESCerts), which can be sold to those failing to meet their targets. This feature creates a market-driven approach to energy efficiency, incentivizing industries to achieve and even exceed their goals. Additionally, the PAT Scheme not only drives energy conservation but also reduces greenhouse gas emissions, aligning with India’s broader sustainability objectives.

• Question 2 of 5 2. Question What is the primary role of Tyrosyl-DNA phosphodiesterase 1 (TDP1)? a) Inducing cell death in healthy cells b) Facilitating protein synthesis in the cytoplasm c) Synthesizing DNA during replication d) Repairing DNA damage induced by Topoisomerase 1 inhibitors Correct Solution: d) Recent research by scientists at the Indian Association for the Cultivation of Science (IACS), Kolkata, has identified a new approach for cancer treatment by targeting a DNA repair enzyme called TDP1. About TDP1: Role: Tyrosyl-DNA phosphodiesterase 1 (TDP1) is a DNA repair enzyme that plays a crucial role in fixing DNA damage induced by Topoisomerase 1 (Top1)inhibitors during cell division. Activation:TDP1 becomes particularly active during the mitotic phase, helping repair drug-induced DNA damage, allowing cancer cells to survive chemotherapy. Regulation:The enzyme’s activity is regulated by Cyclin-dependent kinase 1 (CDK1), which enhances TDP1’s ability to resolve DNA damage through phosphorylation. Significance: Enhanced cancer therapy:Using CDK1 inhibitors with Top1 inhibitors disrupts DNA repair and halts the cell cycle, hindering cancer cell survival. Drug resistance target:TDP1 and CDK1 are new targets for overcoming resistance to current cancer therapies. Precision medicine:Focuses on personalized treatments by targeting cancer cells dependent on these DNA repair proteins. Therapeutic potential:Combining CDK1 inhibitors with existing drugs may boost cancer cell elimination, improving treatment success.

• Question 4 of 5 4. Question Consider the following statements regarding auroras and solar activity: Auroras primarily occur near Earth’s poles due to the trapping of charged particles by Earth’s magnetic field. Auroras can be visible at mid-latitudes during periods of strong solar activity, such as geomagnetic storms. Solar flares and coronal mass ejections (CMEs) reduce the likelihood of auroras being visible. How many of the above statements is/are incorrect? a) Only one b) Only two c) All three d) None Correct Solution: a) Statement 1 is correct because auroras are primarily visible near the poles where Earth’s magnetic field directs charged particles. Statement 2 is also correct as strong solar activity, such as solar flares and CMEs, can expand auroras to mid-latitudes. Statement 3 is incorrect because solar flares and CMEs actually increase the likelihood of auroras being visible, not reduce it. Incorrect Solution: a) Statement 1 is correct because auroras are primarily visible near the poles where Earth’s magnetic field directs charged particles.

• Question 5 of 5 5. Question What is a key limitation of the X-band radar? a) It is ineffective for detecting soil movements b) It only works during daytime c) It has a shorter range due to higher attenuation of the signal d) It cannot detect rain droplets Correct Solution: c) The X-band radar has a shorter range compared to lower frequency bands because its higher frequency leads to greater attenuation of the signal. Despite this limitation, it is highly effective for localized studies, such as monitoring landslides and flood-prone areas. X-band radar is a type of radar that operates within a specific range of frequencies in the electromagnetic spectrum, specifically the X band. According to the Institute of Electrical and Electronics Engineers (IEEE) designation, the X band falls within the 8.0 to 12.0 GHz frequency range, corresponding to wavelengths of approximately 2.5 to 3.75 centimeters. This places it in the microwave part of the spectrum. Key Characteristics: High Resolution: The shorter wavelengths of X-band radar enable it to produce high-resolution images and provide detailed information about detected objects. This makes it excellent for identifying small targets and subtle features. Shorter Range: Compared to lower-frequency radars like S-band radar, X-band radar typically has a shorter effective range. This is because the higher frequency signals are more susceptible to attenuation (weakening) by atmospheric conditions, especially heavy rain and other precipitation. Smaller Antenna Size: For a given gain, X-band radar systems can use smaller antennas compared to lower-frequency radars. This makes them more portable and easier to integrate into various platforms. Sensitivity to Clutter: X-band radar can be more sensitive to clutter, such as reflections from birds, trees, and water bodies, which can sometimes lead to false alarms.
