IT department has introduced which initiative in addition to physical PAN cards?
- Electronic Pan/e-PAN
- Mobile Pan/m-PAN
- Virtual Pan/v-PAN
- None of the above
Answer and Explanation
Answer: A
Explanation
The IT department has issued Permanent Account Number (PAN) within a day to 19,704 newly incorporated companies till March 31, 2017.
In addition to physical PAN card, CBDT has introduced the Electronic PAN (e-PAN) card, which is sent by email to all applicants, including individuals.
Applicant would be benefited by having a digitally signed E-PAN card which they can submit as proof of identity to other agency electronically directly or by storing in the Digital Locker (https://digilocker.gov.in).
The PAN issue was mandated by CBDT, the apex policy making body of the Income Tax department.
The newly incorporated companies have also been issued Tax Deduction Account Number (TAN) simultaneously with PAN as the Central Board of Direct Taxes (CBDT) has tied up with the Ministry of Corporate Affairs (MCA) under which companies can submit a common application form.
Applicant companies submit a common application form SPICe (INC 32) on MCA portal and once the data of incorporation is sent to CBDT by the MCA, PAN and TAN are issued immediately without any further intervention of the applicant.
The Certificate of Incorporation (COI) of newly incorporated companies includes the PAN in addition to the Corporate Identity Number (CIN).
TAN is also allotted simultaneously and communicated to the company.
Till March 31, 2017, 19,704 newly incorporated companies were allotted PAN in this manner.
During March 2017, of the 10,894 newly incorporated companies, PAN was allotted within 4 hours in 95.63 per cent cases and within one day in all cases.
Similarly, TAN was allotted to all such companies within 4 hrs in 94.7 per cent cases and within 1 day in 99.73 per cent cases.

Question No: 282
Which ancient Britain monument is known for its 5,000 year old prehistoric acoustics?
- Tower of London
- Westminster Abbey
- Stonehenge
- None of the above
Answer and Explanation
Answer: C
Explanation
Scientists have developed an app to tap the prehistoric acoustics that swirled around Britain's ancient monument Stonehenge over the last 5,000 years.
A team of researchers spent eight years creating an app that allows you to hear the different noises the stones generated at various points over thousands of years.
While most modern archaeologists generally agree Stonehenge was some sort of prehistoric temple aligned to the movements of the sun, the researchers found the stones also had surprisingly sonorous properties.
This is one of the few human-made places where you’d have heard these kind of acoustic effects."
The app allows listeners to wander amongst the standing stones while listening to an interactive soundscape–including the sound of birds and the wind moving through the stones.

Question No: 283
Which giant planet has been found to have two great spots?
- Saturn
- Neptune
- Jupiter
- Mars
Answer and Explanation
Answer: C
Explanation
Scientists reported 11th April 2017 that the dark expanse of the second Great Spot is 15,000 miles (24,000 kilometres) across and 7,500 miles (12,000 kilometres) wide.
It’s in the upper atmosphere and much cooler than the hot surroundings, thus the name Great Cold Spot.
Unlike giant planet’s familiar Great Red Spot, this newly discovered weather system is continually changing in shape and size.
It’s formed by the energy from Jupiter’s polar auroras.
Scientists were charting the temperature and density of Jupiter’s atmosphere.
When the researchers compared the data with thousands of images taken in years past by a telescope in Hawaii, the Great Cold Spot stood out.
It could be thousands of years old.
The Great Cold Spot is much more volatile than the slowly changing Great Red Spot.

What does PNIPAM stand for, in the context of ferrofluid emulsion?
- poly(N-isopropylacrylamide)
- poly amino(N-isopropylacrylamide)
- polysaccharide(N-isopropylacrylamide)
- polymer(N-isopropylacrylamide)
Answer and Explanation
Answer: A
Explanation
Visual, non-invasive monitoring of body temperature of patients without using a thermometer may become a reality soon, thanks to the work carried out by a team of scientists at Indira Gandhi Centre for Atomic Research (IGCAR), Kalpakkam, near Chennai.
The concept is based on ferrofluid emulsion contained in a thin film that changes colour with rise in temperature within a narrow range - 30-40° C.
The emulsion has iron oxide nanoparticles containing oil droplets dispersed in water.
Till now ferrofluid was used as a magnetic stimuli-responsive material.
Scientists now found that in the presence of a temperature-sensitive polymer - poly(N-isopropylacrylamide), also known as PNIPAM) - the ferrofluid emulsion can be used as a thermally tunable grating to produce different colours.
The adsorbed polymer swells and collapses upon changing the temperature between 32° and 36° C.
This change was clearly manifested as colour change.
From this observation came the novel idea of using PNIPAM-stabilised emulsions as a multistimulii grating.
This is a first of its kind approach where the grating spacing can be tuned either by changing the temperature or by changing the magnetic field strength.
Up to about 34° C, the polymer is highly hydrated and swollen due to repulsive interaction between individual monomer segments.
But when the temperature crosses 34° C, the polymer becomes dehydrated leading to a collapsed state.
The polymer will once again become hydrated and swollen when the temperature falls below 34° C.
Scientists can use additives to tune the collapse of the polymer to higher temperature to reflect fever condition.
Using magnetic fields, the scientists first achieved a particular ordering (spacing between the arrays of emulsion droplets) of emulsion and got a particular colour.
When polymer is added as a stabiliser and the temperature is increased, the grating spacing of the polymer changes and gives rise to a different colour or spacing.
“The colour given off at normal temperature can be fixed by changing the emulsion property and magnetic field strength,” Dr. Philip says.
If the normal temperature is fixed at yellow, the change will be to green when the temperature increases.
Colour with higher wavelength is produced at lower temperature and colour of lower wavelength at higher temperature.
Question No: 285
What is the address of the dedicated website launched by GoI to access 3000 SGI maps publicly?
- http://soinakshe.uk.gov.in/
- http://soginakshe.uk.gov.in/
- . http://sgnakshe.uk.gov.in/
- http://sginakshe.uk.gov.in/
Answer and Explanation
Answer: A
Explanation
The government launched a dedicated website allowing the public the access to download 3,000 maps prepared by the Survey General of India (SGI) but made Aadhaar mandatory for the purpose.
Using Aadhaar number, a person can download three maps every day from the portal (http://soinakshe.uk.gov.in/).
The SGI completes 250 years on April 10, 2017 marking this initiative.
Motto behind making Aadhaar mandatory for using this service was to make it available "only to Indians".
Aadhaar number is a proof of identity and not that of citizenship.
The initiative comes days after Aadhaar was made mandatory for filing Income Tax Returns.
The government is also mulling to make Aadhaar mandatory for booking air tickets.
Government may use alternative solution for backing local manufacturing under GST
SGI: Know More
The SGI has the mandate of making maps and cartographic documents for the country.
It has a wide archive of maps.
The institute first published a 'Map of Hindoostan' in 1783, depicting the subcontinent region comprising India, Pakistan, Burma (now Myanmar), Bangladesh, and parts of Afghanistan.
The SGI has a rich collection of over 5,000 maps. While it made 3,000 maps open to public for download, 1700 will be available for downloading soon
Under the National Map Policy 2005, it had become necessary to make non-defence maps accessible for public.
