Question 5

Kerala is experiencing a significant shift in its traditional industries, such as coir and cashew processing, due to automation and changing global demand. Many workers, especially those with lower skills, are finding it difficult to secure new employment opportunities in emerging sectors like IT or advanced manufacturing, despite available vacancies. Which type of unemployment primarily describes this situation, and what would be a key policy intervention to address it?

Accepted Answer

C. Structural unemployment; investing in vocational training and re-skilling programs. — The scenario describes a mismatch between the skills possessed by the available workforce and the skills demanded by the evolving economy, which is the defining characteristic of structural unemployment. Investing in vocational training and re-skilling programs directly addresses this skill gap by equipping workers for new industries. Cyclical unemployment relates to overall economic downturns, frictional to temporary job transitions, and disguised to surplus labor with zero marginal productivity, none of which are the primary issue described here.

Answer

A. Cyclical unemployment; increasing aggregate demand through fiscal stimulus.

Answer

B. Frictional unemployment; improving job search efficiency through online portals.

Answer

D. Disguised unemployment; promoting self-employment in agriculture.

Question 6

The functional unit of the kidney responsible for filtering blood and forming urine is the:

Accepted Answer

B. Nephron — The nephron is the microscopic functional unit of the kidney, consisting of a renal corpuscle (which includes the glomerulus) and a renal tubule, responsible for filtering blood, reabsorbing useful substances, and excreting waste to form urine. The ureter transports urine, the glomerulus is part of the nephron, and the renal pelvis collects urine before it enters the ureter.

Answer

A. Ureter

Answer

C. Glomerulus

Answer

D. Renal pelvis

Question 8

A patient is advised to reduce saturated fat intake to manage hyperlipidemia. From a biochemical perspective, which of the following lipoproteins is primarily responsible for transporting cholesterol from peripheral tissues back to the liver for excretion or reprocessing, often referred to as 'good cholesterol'?

Accepted Answer

C. High-Density Lipoprotein (HDL) — High-Density Lipoprotein (HDL) is responsible for reverse cholesterol transport, meaning it carries cholesterol from peripheral tissues back to the liver, where it can be excreted or reprocessed. This function helps prevent cholesterol accumulation in arteries, earning HDL the 'good cholesterol' designation. Chylomicrons transport dietary fats, LDL transports cholesterol from the liver to tissues ('bad cholesterol'), and VLDL transports triglycerides from the liver.

Answer

A. Chylomicrons

Answer

B. Low-Density Lipoprotein (LDL)

Answer

D. Very Low-Density Lipoprotein (VLDL)

Question 9

A beam of light passes from air into a glass block with an angle of incidence of 30 degrees. If the refractive index of the glass is 1.5, what is the angle of refraction inside the glass?

Accepted Answer

B. 19.47 degrees — Using Snell's law: n1 sin(θ1) = n2 sin(θ2), where n1=1 (air), θ1=30°, and n2=1.5 (glass). Solving for θ2 gives approximately 19.47 degrees, which is less than the angle of incidence due to light bending toward the normal in the denser medium. The other options are either too small or do not account for the refractive index difference.

Answer

A. 15 degrees

Answer

C. 25 degrees

Answer

D. 30 degrees
