Ex Post Facto study or after-the-fact research is a category of research design in which the investigation starts after the fact has occurred without interference from the researcher. The majority of social research, in contexts in which it is not possible or acceptable to manipulate the characteristics of human participants, is based on Ex Post Facto research designs.

Air Quality Index (AQI) is categorized into six categories, namely: Good, Satisfactory, Moderately polluted, Poor, Very poor, and Severe.
The AQI is proposed for eight pollutants like (Particulate Matter) PM₁₀, (Particulate Matter) PM_2.5, (Nitrogen dioxide) NO₂, (Sulphur dioxide) SO₂, (Carbon monoxide) CO, (Ozone) O₃, (Ammonia) NH3, and (Lead) Pb. So, Chlorofluorocarbons (CFC) is not included.

Hypothesis is a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation. A hypothesis is a tentative statement that proposes a possible explanation to some phenomenon or event.

The pattern is +4, +8, +12, +16 ...
So, missing term = 41 + 20 = 61

"A diagram speaks more than 1000 words." - The statement means that the teacher should use teaching aids in the class.
A diagram can be worth a thousand words, provided it has been well designed and is sufficiently supported.
Instructional diagrams aim to teach students how to:
- perform new tasks,
- improve their existing tasks.
Diagrams should help students to:
- recall the knowledge and skills they have been taught,
- understand the material that is being taught,
- perform problem solving tasks,
- perform transfer tasks.

The most important thing a teacher needs to have within him/her is the knowledge of the subject. If he/she is well versed with the subject, he/she can definitely develop inter-personal relationships at the later stage. Tight handing of students cannot be the reason for failure. Verbal ability is also necessary but knowledge of the subject is more important at every stage of teaching.

Given statement: None but the brave wins the race.

• We’ve to reduce this ‘exclusive proposition’.
• Accordingly, we can write the same statement as:
• all brave are winners, So if this statement is false then,
• All brave persons win the race (False)
• Some persons who win the race are not brave (it can be possible, so it is true)
• Some persons who win the race are brave (False)
• No person who wins the race is brave. (False)
• All brave are not winners = meaning, some persons who win the race are not brave.

Given statement - 'None but the brave wins the race’ implies that only the brave wins the race. The phrase none but can be suitable substituted with the meaning arising out of the word only. But it is also provided that the 'given statement' is false. Therefore, it can be said that a group of people who are winning the race is not exclusively comprised of brave. There can be other categories of people too.
Therefore, on the basis of given alternatives, it will be correct to say that- ​Some persons who win the race are not brave.

Both (A) and (R) are true, and (R) is the correct explanation of (A). Prior to the use of projectors in the classroom, teachers had to spend time writing notes on the board, as well as erasing information as the board filled up. Projectors require a simple click of a button or mouse, thus, freeing valuable class time. By using projectors, teachers can more easily prepare all the notes prior to class for easy presentation. Teachers may also find that they spend less time repeating or rewriting information that is now accessible with a simple click. Hence, projection technology facilitates extensive coverage of course contents.

Every research institute has to enforce research ethics in order to ensure the credibility and meaningfulness of human inquiry

• ICT tools are mainly used by researchers for their ability to ease the knowledge-gathering process and to enhance resource-development. 
• Researchers in general value creativity and originality.
• ICT tools that provide the most open situations with great autonomy to the researcher can really help in identifying and solving research problems in the most creative ways.
• ICT tools help to manage information, protect them, and maintain confidentiality using specific keys.

Connotative words or connotations are the words that are used to express the feelings or expressions in a sentence.

UGC mandated a six‐month module syllabus for UG courses

• In a bid to create awareness among the students regarding the preservation of the environment for future generations, the University Grants Commission (UGC) has asked educational institutes to introduce Environmental Science (EVS) subject in all the undergraduate courses.
• Earlier, as per the directions of the Supreme Court, the UGC had instructed all the universities to include EVS in one semester, but, in a fresh notification, the commission had asked all the universities to compulsorily include a six-month module syllabus on EVS.
• It was introduced in all the undergraduate courses from the academic year, 2019-20.
• For this, the UGC has also recommended an elaborate module syllabus with seven theory units and one practical unit, which includes topics like an ecosystem, biodiversity, deforestation, etc.

So, the six-module course is aimed at making students ecologically aware for a sustainable future and providing first‐hand knowledge on various local environmental aspects.
Therefore the correct statements are  B and C only.

It is clear from the table that 'F' is the only candidate who did not fail in any subject.

Marks obtained by C in English = 72
Marks obtained by F in Maths = 62
Required percentage = 10 × (100/62) = 16.13%

The most popular types of mass media include Newspapers, Radio, Television, Internet, Magazines, etc.
The four functions of mass communications are surveillance, correlation, cultural transmission, and entertainment.
The Media and Its Function

• Information.
• Media provides education and information. 
• The other important function of media is entertainment. 
• Persuasion, it is another function of mass media. 
• Surveillance denotes observation. 
• Interpretation. 
• Linkage. 
• Socialization.
• Political Awareness.

So, passing messages without checking credibility is not the function of mass media.

An operating system (OS) is system software that manages computer hardware and software resources and provides common services for computer programs. Windows and UNIX are the examples of Operating system.

Media that exist in an interconnected series of communication - points are referred to as Networked media.

• Network communication, or internetworking, defines a set of protocols (that is, rules and standards) that allow application programs to talk with each other without regard to the hardware and operating systems where they are run.
• Network media refers to the communication channels used to interconnect nodes on a computer network.
• Typical examples of network media include copper coaxial cable, copper twisted-pair cables and optical fiber cables used in wired networks, and radio waves used in wireless data communications networks.
• Network media is the actual path over which an electrical signal travels as it moves from one component to another. This chapter describes the common types of network media, including twisted-pair cable, coaxial cable, fiber-optic cable, and wireless.

It refers to the tracing and recovery of specific information from stored data.

From the above discussion, it can be observed that the correct answer is Option (A).

LAN stands for Local Area Network. It is a computer network that links devices within a building or group of adjacent buildings, especially one with a radius of less than 1 km.

Therefore, from the above explanation, it is clear that option (C) is the correct answer.
