Question 1 of 5
1. Question
2 pointsConsider the following statements:
1. The alignment of the Line of Actual Control in the western sector in Ladakh is along the McMahon Line.
2. Depsang Plains are situated towards the north-west of Daulat Beg Oldie.
3. Hot Springs and Gogra are located near the LAC in Ladakh region.
How many of the above statements are correct?Correct
Answer: A
Explanation:
● Statement 1 is not correct: Line of Actual Control (LAC) is the demarcation that separates Indian-controlled territory from Chinese-controlled territory. India considers the LAC to be 3,488 km long, while the Chinese consider it to be only around 2,000 km. It is divided into three sectors: the eastern sector which spans Arunachal Pradesh and Sikkim, the middle sector in Uttarakhand and Himachal Pradesh, and the western sector in Ladakh. The alignment of the LAC in the eastern sector is along the 1914 McMahon Line.
● Statement 2 is not correct: Depsang Plains is located just 30 kilometres southeast of India’s critical Daulat Beg Oldie post near the Karakoram Pass in the north. In contrast to the mountainous terrain of the region, the flat surface of the plains also offers a potential launchpad for military offensives by either country.
● Statement 3 is correct: At present, seven friction points exist in eastern Ladakh. These include PP 14 (Galwan), PP 15 (Hot Springs), PP 17A (Gogra), the north and south banks of Pangong Tso, the Depsang Plains, and Charding Nullah in Demchok.Incorrect

Question 2 of 5
2. Question
1 pointsConsider the following statements:
- Basaltic rock is a kind of volcanic rock that is rich in calcium and magnesium.
- Basaltic rocks are found in the Rajmahal Trap region of Jharkhand and West Bengal.
- Basaltic dust enriches the soil as well as accelerates carbon sequestration.
How many of the above statements are correct?
Correct
Answer: C
Explanation:
- Statement 1 is correct: Basaltic rock, a kind of volcanic rock, is rich in minerals such as calcium and magnesium.
- Statement 2 is correct: Many parts of Maharashtra and Gujarat, where the volcanic Deccan Traps are located, are rich in such basaltic rock as parts of Jharkhand and West Bengal where the Rajmahal Traps are situated. The latter are regularly mined for construction.
Statement 3 is correct: Being an organic fertiliser, the basaltic dust enriches the soil as well as accelerates carbon sequestration

Question 3 of 5
3. Question
1 pointsRecently, Global Iodine Deficiency Disorders Prevention Day was observed in October 2024. In this context, consider the following statements with reference to Iodine:
- It is an essential component of the thyroid hormones.
- Iodide is the only form of iodine that is not absorbed by the stomach.
- Hypothyroidism and goitre are caused due to excess iodine intake.
How many of the above statements are correct?
Correct
Answer: A
Explanation:
- Statement 1 is correct: Iodine is an essential component of the thyroid hormones, thyroxine (T4) and triiodothyronine (T3), which regulate metabolism and are crucial for fetal and infant development.
- Statement 2 is not correct: Found in foods and iodized salt, iodine exists in several forms, including sodium and potassium salts, inorganic iodine (I2), iodate, and iodide. Iodide, the most common form, is quickly absorbed in the stomach and used by the thyroid for hormone production. Most excess iodide is excreted through urine.
- Statement 3 is not correct: Iodine deficiency has multiple adverse effects on growth and development and is the most common cause of preventable intellectual disability in the world. Iodine deficiency disorders result from inadequate thyroid hormone production secondary to insufficient iodine. During pregnancy and early infancy, iodine deficiency can cause irreversible effects. If a person’s iodine intake falls below approximately 10–20 mcg/day:
- Hypothyroidism occurs, a condition that is frequently accompanied by goitre
- Goitre is usually the earliest clinical sign of iodine deficiency

Question 4 of 5
4. Question
1 pointsConsider the following statements with reference to Amylase Enzyme:
- It is predominantly secreted by the pancreas and salivary glands.
- Its primary role is transforming complex carbohydrates into simpler sugars.
- Among the living things, it is present only in humans and animals.
How many of the above statements are correct?
Correct
Answer: B
Explanation:
- Statement 1 is correct: Amylase is a digestive enzyme predominantly secreted by the pancreas and salivary glands and is present in other tissues at minimal levels.
- Statement 2 is correct: The primary role of amylases is to break down the glycosidic bonds within starch molecules, transforming complex carbohydrates into simpler sugars.
Statement 3 is not correct: Amylase enzymes are categorized into 3 main classes, alpha, beta and gamma amylases—each targeting distinct segments of the carbohydrate molecule. Alpha amylase is present in humans, animals, plants, and microbes, whereas beta amylase is primarily found in microbes and plants. Gamma amylase, on the other hand, can be located in both animals and plants.
