Higher Education System
Central university : Central universities or union universities in India are established by an Act of Parliament and are under the purview of the Department of Higher Education in MoE. In general, universities in India are recognized by UGC, which draws its power from the UGC Act 1956.
As of 31 March 2021, the list of central universities E.g., Jamia Milia Islamia is a central university.
State universities : State universities are run by the respective state government of the states and union territories of India, and are usually established by a local legislative assembly act. Panjab university is considered both central and state university.
Deemed universities : The Governor of the State is the chancellor of deemed universities. The status of a deemed to be university allows full autonomy in courses, syllabus, admission and fees. According to the new norms in January, 2019, applicant institution must be in operation for at least 20 years, have 100 teachers and 2,000 students, a minimum teacher-student ratio of 1:20 to get deemed university status, One-third of the students should be pursuing research or post-graduate courses.
Private Universities : Private universities are approved by the UGC. They can grant degrees but are not allowed to have off-campus affiliated colleges.
Autonomous institutes : Apart from the above universities, other institutions are granted the permission to autonomously award degrees. These institutes do not affiliate colleges and are not officially called universities but autonomous organisations or autonomous institutes. They fall under the administrative control of the Department of Higher Education, MoE.
These organisations include the Indian Institutes of Technology, the National Institutes of Technology, the Indian Institutes of Science Education and Research, the Indian Institutes of Engineering Science and Technology, the Indian Institutes of Management, the National Law Schools, the All-India Institute of Medical Science, and other autonomous Institutes.

Ques 22: What is the name for the technique which uses images that are often more evocative than words, and more precise and potent in triggering a wide range of associations and thinking ?

  • Brainstorming
  • Mind-mapping
  • Story boarding
  • Synectics

Information and Communication Technology
Mind mapping : A mind map is a diagram used to visually organize information. A mind map is hierarchical and shows relationships among pieces of the whole. It is often created around a single concept, drawn as an image in the centre of a blank page, to which associated representations of ideas such as images, words and parts of words are added. Major ideas are connected directly to the central concept, and other ideas branch out from those major ideas.
Thus, mind mapping is the technique which uses images that are often more evocative than words and are precise and potent in triggering a wide range of association and thinking patterns.

Ques 24: If the selling price of 24 results in a discount of on the list price, what selling price would result 30% discount on list price ?

  • 18
  • 20
  • 21
  • 27

Mathematical Aptitude and Reasoning
The discount offered on the article = 20%
SP = 24
We can calculate the CP
24⨯(100+20)/100 = 30
If 30% discount is offered, then
SP = 30⨯(100-30)/100 = 30⨯70/100 = 21

People, Development and Environment
In agricultural area, groundwater can contain significant concentration of the nitrate pollutant. When pollutants released on the Earth’s surface enter the groundwater, it leads to groundwater pollution. Pollution can result from workplace sanitation systems, landfills, waste from wastewater treatment plants, sewer leaks, petrol filling stations, or overuse of fertilizers in agriculture. Therefore, groundwater in agricultural areas can contain significant amounts of the nitrate pollutant.
Cadmium : Cadmium is a chemical element with the symbol Cd and atomic number 48.
Lead : Lead is a naturally occurring toxic metal found in the Earth’s crust. Its widespread use has resulted in widespread environmental pollution, human exposure and public health problems in many parts of the world.
Selenium : Selenium is a toxic element and its high concentration is not only harmful to the environment but also to human health. It causes thyroid disorders, viral infections, preeclampsia (high blood pressure), swelling, etc.

Ques 29: In agricultural regions, groundwater can have significant concentrations of which pollutant ?

  • Cadmium
  • A,B,C and D only
  • B,C and E only
  • B,C,D and E only

People, Development and Environment
Greenhouse gases are atmospheric gases that absorb and emit radiation within the thermal infrared range, thereby contributing to the greenhouse effect and global climate change. Many different greenhouse gases are produced as a result of human activities, including :
1. Carbon dioxide (CO2)
2. Methane (CH4)
3. Nitrous Oxide (N2O)
4. Hydrofluorocarbons (HFCs)
Perfluorinated compounds :
5. Sulphur Hexafluoride (SF6)
6. Nitrogen trifluoride (NF3)
7. Perfluorocarbons (PFCs)
8. Fluorinated Ether (HFE)
9. Per-Flouro Poly Ether (PFPE)
10. Chlorofluorocarbons (CFCs)
11. Hydrochlorofluorocarbons (HCFC)

Even water is a GHG.
At the Rio Earth Summit in 1992, international negotiators adopted the United Nations Framework Convention on Climate Change (UNFCCC). UNFCCC aims to prevent dangerous human interference with the climate system by stabilizing atomospheric concentrations of GHGs at safe levels. The UNFCCC itself has not set any mandatory limits on GHG emissions for india vidal countries and has no enforcement mechanism instead, the UNFCCC provides updates (the ‘protocol) that set mandatory limits. The Kyoto Protocol was adopted in 1997 and came into force in 2005. In set GHG emission reduction targets for a set of industrialized countries. These targets have been implement in the emission reduction commitment period with the first period from 2008 to 2012 and the second periofied the UNFCCC and its Kyoto Protocol.
The Kyoto Protocol aims to cut GHG emissions in the developed world by about 5% by 2012 compared 1990 levels. In india, the Kyoto Protocol was implemented in February 2005. Kyoto Protocol applies 6 greenhouse gases; Carbon dioxide (CO2), methane met and (CH4) nitrous oxide (N2O), hydrofluorocarboide (SF6). The seventh gas nitrogen trifluoride (NH2) was added at a later stage.
The Intergovernmental Panel on Climate Chan (IPCC) has been assisting the UNFCCC in setting national goals to develop a scientific summary the climate system and the physical basis of climate change. This summary is updated from time to time and published in the IPCC Assessment Report. The Sixth Report (AR6) was published in the year 2021.
The IPCC. AR establishes values for the Global Warming Potential of various green gases. GWP values describe the radiative effect of a given unit of GHG relative to (in comparison to) one unit of CO2.
According to the latest development, the world has set the year 2050 as the threshold for achieving the Zero Emissions target.
