VFA Mixed Practice Test #51

Question 1

The Kerala Agrarian Relations Bill, 1957, despite being a landmark legislative attempt, did not achieve immediate widespread implementation in its original form. What was the primary reason for this delay and subsequent re-enactment?

Accepted Answer

C. Constitutional challenges and a presidential intervention led to its eventual striking down and subsequent re-enactment in a modified form. — The Kerala Agrarian Relations Bill, 1957, was initially struck down following constitutional challenges and a presidential intervention, which necessitated its re-enactment as the Kerala Agrarian Relations Act, 1960. This legal and political hurdle was the primary reason for its delayed implementation in its original form. Options A, B, and D do not accurately reflect the main reason for the bill's initial failure to be implemented.

Answer

A. Lack of political will from the ruling government to enforce its provisions against powerful vested interests.

Answer

B. Widespread peasant revolts and tenant protests against the bill's perceived inadequacies.

Answer

D. The severe financial crisis in Kerala made it impossible to fund the compensation required for land acquisition.

Question 2

Despite its immense popularity in several Commonwealth nations, cricket has only made sporadic appearances in the Olympic Games, with efforts ongoing for its re-inclusion. Considering the demands of a multi-sport event, which format of cricket is most widely discussed for potential Olympic inclusion, and why?

Accepted Answer

C. Twenty20 (T20) cricket, owing to its shorter duration, fast-paced action, and appeal to a broader global audience. — Twenty20 (T20) cricket is the most widely discussed format for Olympic inclusion because its shorter duration (around 3 hours per match) fits well within the tight scheduling constraints of a multi-sport event. Its fast-paced, high-scoring nature is also more appealing to a diverse global audience and aligns with the Olympic desire for dynamic, accessible sports. Test and ODI formats are too lengthy for the Olympics, and 'The Hundred' is a relatively new, regionally specific format, less likely for global adoption at this stage.

Answer

A. Test Cricket, due to its historical significance and comprehensive display of skill.

Answer

B. One-Day Internationals (ODIs), offering a balanced duration and strategic depth.

Answer

D. The Hundred, as a newer, even shorter format designed for explosive entertainment.

Question 4

A worker pushes a 50 kg box across a rough horizontal floor with a constant applied force of 200 N. If the coefficient of kinetic friction between the box and the floor is 0.2, and the box moves 10 meters, what is the net work done on the box? (Take acceleration due to gravity g = 10 m/s²)

Accepted Answer

A. 1000 J — The net work done on an object is the sum of work done by all forces acting on it. The applied force does W_applied = F_applied × d = 200 N × 10 m = 2000 J. The normal force is N = mg = 50 kg × 10 m/s² = 500 N. The kinetic frictional force is F_friction = μ_k × N = 0.2 × 500 N = 100 N. The work done by friction is W_friction = -F_friction × d = -100 N × 10 m = -1000 J (negative as it opposes motion). Therefore, the net work done is W_net = W_applied + W_friction = 2000 J - 1000 J = 1000 J. This net work done also equals the change in kinetic energy of the box.

Answer

B. 2000 J

Answer

C. 500 J

Answer

D. 0 J

Question 9

A microbiologist performs a Gram stain on a bacterial sample. The primary purpose of this staining technique in bacteriology is to:

Accepted Answer

B. Differentiate bacteria based on their cell wall composition. — Gram staining is a differential staining technique that classifies bacteria into two major groups, Gram-positive and Gram-negative, based on differences in their cell wall composition and structure. It does not determine motility, identify spores, or assess metabolic activity.

Answer

A. Determine the motility of bacteria.

Answer

C. Identify the presence of bacterial spores.

Answer

D. Assess the metabolic activity of bacteria.
