1. Consider the following statements.
1. Application of Raman scattering can be used to find the temperature of Power lines.
2. Raman thermometry may prove to be more efficient than “thermal cameras” in finding the temperature of Power lines.
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-C
Explanation-
Statement 1 is correct.
In Raman effect, when light is scattered off an object , two bands are observed- Stokes and Anti-stokes Band.
Anti-stokes components of Raman scattering are strongly dependent on the temperature that the material is subjected to.Thus, by measuring the intensity of Anti-stokes components of Raman scattering ,the temperature can be estimated.
Statement 2 is correct.
 Use of Raman thermometry to measure temperature of power lines can be cost effective as well as can provide real time information ,compared to existing method of using “thermal cameras.”


2. Consider the following pairs:
Vaccine            Type of Antigen used
1. Viral Vector vaccines        Killed Germs
2. Inactivated vaccines        Modified version of different germs
Which of the pairs given above is/are correctly matched?
(a) 1 only.
(b) 2 only.
(c) Both 1 and 2.
(d) Neither 1 nor 2.
Answer-D
Explanation-
Pairs 1 and 2 are incorrect.
All vaccines contain an active component (the antigen) which generates an immune response, or the blueprint for making the active component. The antigen may be a small part of the disease-causing organism, like a protein or sugar, or it may be the whole organism in a weakened or inactive form.
Inactivated vaccines use the killed version of the germ that causes the disease. Viral vector vaccines use a modified version of a different virus as a vector to deliver protection.


 3. Consider the following statements regarding MSP (Minimum support price):
1. MSP is announced for all cereal crops and also for sugarcane.
2. The Ministry of Agriculture & Farmers’ welfare recommends the MSPs for all the crops.
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-D
Explanation-
Statements 1 and 2 are incorrect.
 Sugarcane is not among the crops that MSP provides. It is provided Fair and Remunerative prices.
The Commission for Agricultural Costs and Prices (CACP) recommends the MSPs.

 4. Consider the following statements regarding “Enforcement Directorate.”
1. It has power to enforce both civil and criminal law.

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-A
Explanation-
It has power to enforce both civil and criminal law under Foreign exchange management act and Prevention of money laundering act.
An appeal against the PMLA court can be filed in the High court.

5. In which of the following areas, Artificial Intelligence can be possibly used?
1. Agriculture
2. Industry
3. Security
4. Environment Conservation
5. Public Service delivery

(a) 1, 2 and 3 only
(b) 2, 3 and 4 only
(c) 1 and 5 only
(d) 1, 2, 3, 4 and 5
Answer-D
