The Current Affairs questions are based on sources like ‘The Hindu’, ‘Indian Express’ and ‘PIB’, which are very important sources for UPSC Prelims Exam. The questions are focused on both the concepts and facts. The topics covered here are generally different from what is being covered under ‘Daily Current Affairs/Daily News Analysis (DNA) and Daily Static Quiz’ to avoid duplication. The questions would be published from Monday to Saturday before 2 PM. One should not spend more than 10 minutes on this initiative.

Which of the above statements is/are correct?
Solution (b)
Parivahan – Sewa project was the flagship project initiated by the Centre in the light of a new amendment to rule 139 of the Central Motor Vehicles Rules, 1989, which validated the electronic form of motor vehicle documents.
The web-based software, called Parivahan/Vahan, developed by the National Informatics Centre and controlled by the Centre Road Transport Ministry consisted of numerous modules and one such module is ‘Blacklist’, which includes the vehicle numbers and licence numbers having audit objections, complaints, court cases and check reports.
The provisions incorporated in the Central Motor Vehicles Rules, 1989 ensured that sufficient details were included on the portal so as to caution the public at large in respect of the vehicle involved in any crime or cases.

With reference to rooftop photovoltaic solar energy, consider the following statements:
Which of the above statements is/are correct?
Solution (d)
Rooftop mounted systems are small compared to ground-mounted photovoltaic power stations with capacities in the megawatt range, hence being a form of distributed generation. Most rooftop PV stations in developed countries are Grid-connected photovoltaic power systems. Rooftop PV systems on residential buildings typically feature a capacity of about 5 to 20 kilowatts (kW), while those mounted on commercial buildings often reach 100 kilowatts to 1 Megawatt (MW). Very large roofs can house industrial scale PV systems in the range of 1-10 Megawatts.
Rooftop PV solar operation and maintenance is of higher costs in comparison with ground-based facilities due to the distributed nature of rooftop facilities and harder access. In rooftop solar systems it typically takes a longer time to identify a malfunction and send a technician, due to lower availability of sufficient photovoltaic system performance monitoring tools and higher costs of human labor.
A global study has found that India is the most cost-effective country for generating rooftop solar energy at $66 per megawatt-hour, while the cost in China is marginally higher at $68 per megawatt-hour.

Consider the following statements:
Which of the above statements is/are correct?
Solution (b)
In order to stabilize global warming at any level, emissions of carbon dioxide, the main greenhouse gas, need to be eliminated; reducing them is not enough. Other greenhouse gases such as methane also need to be constrained.
However, in sectors such as agriculture and aviation, bringing emissions to zero may not be possible. Therefore, the only approach is to draw sufficient greenhouse gases from the atmosphere to balance out emissions that remain – so that emissions reach ‘net zero’.
If negative emissions and positive emissions are balanced, global warming should stabilise. Currently the only greenhouse gas for which negative emissions are feasible at scale is carbon dioxide.

Consider the following statements:
Which of the above statements is/are correct?
Solution (b)
Under the terms of the nuclear deal, Iran was prohibited from enriching uranium above 3.67% with the exception of its research reactor activities. Enriched uranium above 90% can be used in a nuclear weapon.
In September, the International Atomic Energy Agency said Iran’s stockpile of uranium enriched to up to 20% fissile purity was estimated at 84.3 kg up from 62.8 kg three months earlier.
Scientists estimate that at least 170 kg of enriched uranium is needed to make a bomb.
The nuclear deal known as the Joint Comprehensive Plan of Action, or JCPOA, promises Iran economic incentives in exchange for limits on its nuclear programme, and is meant to prevent Tehran from developing a nuclear bomb.

The first stage in making a GM plant requires transfer of DNA into a plant cell. In this regard, consider the following statements:
Which of the above statements is/are correct?
Solution (c)
Karnataka is witnessing a fresh round of opposition to Genetically Modified (GM) crops and technology with various groups comprising farmers, organic farming associations, and experts petitioning the government against issuing no-objection certificate (NOC) to a private company to carry out restricted field trials of Bt cotton and Bt maize.
On rare occasions, the process of DNA transfer can happen without deliberate human intervention. For example the sweet potato contains DNA sequences that were transferred thousands of years ago, from Agrobacterium bacteria into the sweet potato genome.
