SMS
Bluetooth is a short-range wireless technology used for data and voice communication between electronic devices. GPRS is a cellular data service, WAP is a protocol for mobile web access, and SMS is used for text messaging, not short-range device-to-device communication.
If force is expressed in Newton and the distance in metre, then the work done is expressed in
A)
Joule
B)
Kg wt
C)
Kg wt m
D)
Watt
Work done = force × distance. If force is in Newton and distance in metre, the unit becomes N m, which is defined as 1 Joule. Kg wt and Kg wt m are gravitational units, and Watt is the unit of power, not work.

Optical fibre works on the
A)
principle of refraction
B)
total internal reflection
C)
scattering
D)
interference
An optical fibre guides light by repeatedly reflecting it inside the core when the light strikes the core-cladding boundary at an angle greater than the critical angle. This phenomenon is called total internal reflection. Refraction alone does not keep light trapped in the fibre, and scattering or interference are not the operating principle.
A.P.J.Abdul Kalam, excluding the acting, was the President of India
A)
9th
B)
10th
C)
11th
D)
12th
A.P.J. Abdul Kalam was the 11th President of India overall, but the question says "excluding the acting". If acting Presidents are not counted, he becomes the 10th President. Hence option (b) is correct. Option (c) would be the answer if acting Presidents were included.
The minimum age to qualify for election to the Lok Sabha is

25 years
B)
21 years

D)
35 years
Under Article 84 of the Indian Constitution, the minimum age for becoming a member of the Lok Sabha is 25 years. Hence, option (a) is correct. Option (b) 21 years was the earlier voting age, not the eligibility age for Lok Sabha. Option (c) 18 years is the current voting age. Option (d) 35 years is the minimum age for the Rajya Sabha, not the Lok Sabha.

A)
Assam
B)

Nagaland
The Sangai Festival is organised in Manipur. It is named after the Sangai, the state animal of Manipur. The other options are incorrect because Assam, Mizoram, and Nagaland have their own respective state festivals.
If the plane of the earth’s equator were not inclined to the plane of the earth’s orbit
A)
the year would be longer
B)
the winters would be longer
C)
there would be no change of seasons
D)
the summers would be warmer
The change of seasons happens because the Earth's axis is tilted relative to the plane of its orbit around the Sun. This tilt causes different parts of the Earth to receive varying amounts of sunlight during the year. If the plane of the Earth's equator were not inclined to the plane of the Earth's orbit, there would be no axial tilt effect, so the Sun’s rays would fall more or less equally throughout the year at each place. Hence, there would be no change of seasons. The other options are incorrect because the length of the year does not depend on axial tilt, and warmer summers or longer winters are consequences of the tilt, not its absence.
Which of the following is not covered under Article 371G of the Constitution of India, a special provision with respect to the state of Mizoram?
A)
Religious and social practices of the Mizos

Wealth tax is not among these protected subjects, so the correct answer is Wealth tax.
Nuclear power is __________ thermal power.
A)
cheaper than
B)
costlier than
C)
equal in amount
D)
they cannot be related
Nuclear power plants require very high capital investment, specialized safety systems, radioactive fuel handling, and costly waste disposal, so they are generally considered costlier than conventional thermal power plants. Thermal power is usually cheaper to establish and operate compared to nuclear power. Therefore, the correct answer is 'costlier than'.
In which of the following states no community has been specified as a scheduled tribe?
A)
Chandigarh and Delhi

By contrast, Delhi and Chandigarh have no Scheduled Tribe communities specified in the Union Territory context, but the standard exam answer for the states asked here is Haryana and Punjab. Goa and Mizoram/Meghalaya do have Scheduled Tribe communities specified.

C.V. Raman is the only Indian who won the Nobel Prize in Physics, awarded in 1930 for his work on the scattering of light, known as the Raman Effect. J.C. Bose made pioneering contributions to physics and biology but did not receive the Nobel Prize. Vikram Sarabhai and H.J. Bhabha were eminent Indian scientists, but neither won the Nobel Prize in Physics.

A)
a sovereign, socialist and democratic republic
B)
a sovereign, socialist, secular and democratic republic

a socialist, secular and democratic republic
The Preamble of the Constitution of India, after the 42nd Amendment, describes India as a 'Sovereign Socialist Secular Democratic Republic'. Among the given options, option (b) matches this wording best. Option (a) is incorrect because it omits 'secular'; option (c) is not the Preamble’s wording; and option (d) is also incomplete because it omits 'sovereign'.
The filament of an electric bulb is made of
A)
tungsten
B)
nichrome
C)
graphite
D)
iron
The filament of an electric bulb is made of tungsten because it has a very high melting point and can glow white-hot without melting. Nichrome is mainly used in heating elements, graphite is used in electrodes, and iron is not suitable for bulb filaments because it melts at a much lower temperature.
LPG consists of mainly
A)
methane, ethane and hexane
B)
ethane, hexane and nonane
C)
methane, hexane and nonane
D)
methane, butane and propane
LPG (liquefied petroleum gas) is mainly a mixture of propane and butane, with traces of other light hydrocarbons. Among the options, (d) is the only one that includes propane and butane, so it is the correct choice. The other options contain higher alkanes like hexane and nonane, which are not the main constituents of LPG.
Liquids transmit pressure equally in all directions. This is known as
A)
Boyle-Pascal’s Law
B)
Pascal’s Law
C)
Archimedes’ Principle
D)
None of these
Liquids transmit pressure equally in all directions, which is the statement of Pascal’s Law. It says that pressure applied to a confined fluid is transmitted undiminished and equally throughout the fluid. Boyle-Pascal’s Law is not the standard name for this principle, and Archimedes’ Principle deals with buoyancy, not pressure transmission.
A sudden, shortlived decline in economic activity followed by a sharp fall in production and rise in unemployment is termed as
A)
Stagflation
B)
Recession
C)
Deflation
D)
Depression
A recession is a sudden, short-lived decline in economic activity, usually marked by falling production, income, and rising unemployment. Stagflation means slow growth with inflation, deflation means a fall in the general price level, and depression is a much deeper and more prolonged downturn than a recession.

C)
Bhaskara I
D)
Albert Einstein
India’s first satellite was named Aryabhata, after the ancient Indian mathematician and astronomer Aryabhata. Among the given options, this corresponds to option (a) Aryabhatta. The other options are incorrect because Bhaskara I and Bhaskara II were later Indian satellites, and Albert Einstein was not the name of India’s first satellite.
