Kerala SET Paper 1 Mock Test - 5 - KTET MCQ

The Second Law of Motion states that if an unbalanced force acts on a body, that body will experience acceleration ( or deceleration), that is, a change of speed.

 One can say that a body at rest is considered to have zero speed, ( a constant speed). So any force that causes a body to move is an unbalanced force. Also, any force, such as friction, or gravity, that causes a body to slow down or speed up, is an unbalanced force. 

Sri Lanka is separated from India by a narrow channel of sea formed by the Palk Strait and the Gulf of Mannar.

Renewable energy is regenerative or, for all intents and purposes, practically endless energy.
Examples of renewable energy sources are solar energy, wind energy, hydropower, biomass, geothermal energy, and ocean energy.
Characteristics of Renewable energy are the following: 

• These resources have the ability to regenerate.
• Because they are replenished in tandem with exploitation, they are constantly available for use.
• On a time scale, the regeneration of these sources involves some ecological processes.
• If renewable resources are utilized faster than the ecosystem can replenish them, they become nonrenewable.
• These resources include food, timber, raw materials for textiles, leather, and so on. Oxygen, freshwater, solar energy, and biomass are among them.
• Increased use of renewable energy could reduce the usage of fossil fuels (coal, petroleum, and natural gas),
• It can reduce air pollution and CO2 emissions while also contributing to national energy independence and economic and political security.

Thus, the need for elaborate arrangements for transport is not true regarding Renewable energy.

Hydrological Cycle

• The process of circulation of water within the hydrosphere of Earth in different forms such as liquid, solid and gaseous states are called the Hydrological Cycle of water.
• It starts with the Evaporation of water from the surface of the water bodies and further, it includes Transpiration, Sublimation, Condensation and Precipitation.

Key Points

'Hydrological cycle' steps

• The first step of the water cycle is evaporation from water bodies means the part of the Hydrosphere.
• The second step of the water cycle is condensation, which takes place in the atmosphere.
• The third step of the water cycle is precipitation and runoff means the part of the lithosphere.
• The final step of the water cycle is in the Biosphere. 
• It is the zone where all the spheres interact and work together.
• It includes processes like water uptake and transpiration by plants.

​

Thus, in the 'Hydrological cycle' the order of the source in which they connected from each other is first Hydrosphere, second Atmosphere, third Lithosphere and fourth Biosphere.

Additional Information

Processes during a hydrological cycle:

​​Evaporation

• When waters convert from liquid to gas stage as it moves from the groundwater into the atmosphere, this phenomenon is called Evaporation.
• Mainly Solar radiation is the source of energy for evaporation. 

Transpiration

• When plant uptake of water at the roots, transport of water through plant tissues, and release of vapour by leaves is known as transpiration.

Condensation

• The Process of conversion of water vapour to liquid water droplets in the air is called Condensation.
• It is responsible for the formation of fog and clouds.

​Precipitation

• When the condensed water vapour falling to the surface of the Earth is known as Precipitation.
• It occurs in the form of rain, snow, and hail.
• It provides for the delivery of atmospheric water to the earth in the form of rain.

Global warming during winter becomes more pronounced at the tropic of capricorn.
The five major circles of latitude are, from north to south:

• The Arctic Circle (66º33'38"N)
• The Tropic of Cancer (23º26'22"N)
• The Equator (0ºlatitude)
• The Tropic of Capricorn (23º26'22"S) Global warming during winter
• The Antarctic Circle (66º33'38"S)

Tropic of Cancer at which the Sun appears directly perpendicular on June 21 in an event that is called Summer Solstice.

Given:
Total number of players participating in cricket from Canada, Spain and USA
= 80+70+60 = 210
Total number of players participating in Football from India, UK and Australia
= 65+70+90 = 225
Total number of players participating in cricket from Canada, Spain and USA and in football from India, UK and Australia
= 225+210 = 435
∴ The total number of players is 435.

Fundamental research:

• Also known as basic or pure research
• Concerned with generalizations and with the formulation of a theory
• Finding information for the addition of knowledge
• Developing an effective explanation through theory building 
• Mostly academic research
• Extensive in nature. 
• The goal of inquiry in fundamental research is directed at bringing an increment in the fund of knowledge.
• Example: some natural phenomenon

Action research:

• The term 'Action research' first coined by Kurt Lewin in 1944 and described in his paper "Action Research and Minority Problems" published in 1946.
• According to Lewin, "a comparative research on the conditions and effects of various forms of social action and research leading to social action" that uses "a spiral of steps, each of which is composed of a circle of planning, action, and fact-finding about the result of the action".
• Action research is participatory in nature. It means ‘learning by doing’.
• It generates democratic impulse, simultaneous contribution to social science (knowledge), and social change (practice).
• For example, research on the educational situation, as well as the practitioner of education, undergo a change for the better.

Therefore, Both Statement I and Statement II are true

Regur soil which is also known as cotton soil.
It is ideal for the growth of cotton because of the following reasons:
(i) Black soil is clayey in nature.
(ii) It contains a high proportion of calcium and magnesium carbonates.
(iii) It isFertile
(iv) It have high moisture holding capacity.

The correct answer is A and R both are true and R is the correct explanation of A.

Key Points

Trees as a shelter for animals:

• Trees provide shelter and food for a variety of birds and small animals, such as squirrels and beavers.
• Enhancing growth diversity, trees create an environment that allows the growth of plants that otherwise would not be there.
• Flowers, fruits, leaves, buds, and woody parts of trees are used by many different species.
• Deforestation can directly lead to biodiversity loss when animal species that live in the trees no longer have their habitat, cannot relocate, and therefore become extinct. 

Deforestation can lead certain tree species to permanently disappear, which affects the biodiversity of plant species in an environment.

Hence, the reason is also correct.

Important Points

Human activities that influence the extinction and endangerment of wild species fall into a number of categories:

• ​Land use practices like Deforestation, Projects in urban and suburban development, agriculture, and water management projects that encroach upon and destroy natural habitats.
• Unsustainable hunting and harvesting result in higher rates of death than new individual recruitment.
• Ecological damage caused by water, air, and soil pollution.
• Anthropogenic (human-caused) global climate change.
• ​According to the India State of Forest Report (ISFR) 2019, The forest and tree cover in the country is estimated at 80.73 million hectares, which is 24.56 percent of the total geographical area.​

Additional Information

The International Union of Conservation of Nature and Natural Resources (IUCN):

• For the purposes of conservation, the IUCN has divided the threatened plant and animal species into 9 categories.
• Endangered Species: It includes those species which are in danger of extinction. The IUCN's Red List of Threatened Species provides information about endangered species around the world.
• Vulnerable Species: This includes the species which are likely to be in danger of extinction in the near future if the factors threatening their extinction continue.
• Rare Species: The population of these species is very small in the world; they are confined to limited areas or thinly scattered over a wider area.

From the line given in the passage: On India walking away from the Regional Comprehensive Economic Partnership, the external affair minister said no agreement was better than having a bad agreement.

Essay type questions do not provide scope to assess the students objectively. Mrs. Suman is using essay type questions. These questions are subjective in nature and their answers vary from subject to subject; whereas multiple choice questions, true/false type questions, or one word answer type questions are used to assess the students objectively.

From Statement 1:
H sits to the immediate right of D.
Two persons sit between D and F.
A is an immediate neighbour of M, who sits to the immediate right of F.

So, H sits to the immediate left of N.
The data in Statement I alone is sufficient to answer the question.
From Statement 2:
F and N are immediate neighbours and M sits immediate right of F.
A sits third to the left of N.
Here, we can not determine who sits immediate left of N.

Hence, option A is the correct answer.

(i) The COD (Chemical oxygen demand) test is used to measure the content of organic matter of waste water, both biodegradable and non-biodegradble.

(ii) The COD test uses potassium dichromate (K₂Cr₂O₇) in presence of concentrated sulfuric acid (H₂SO₄) solution that oxidizes both organic (predominate) and inorganic substances in a waste water sample.

(iii) The reagents for COD test are followings:

• Standard potassium dichromate solution (0.25N)
• Concentrated sulfuric acid
• Standard ferrous ammonium sulphate titrant (0.1N)
• Ferroin indicator solution.

The National Literacy Mission (NLM) is a nationwide program started by Government of India in 1988 with the approval of the Cabinet as an independent and autonomous wing of the Ministry of HRD (the then Department of Education). It aims to educate 80 million adults in the age group of 15–35 over an eighty-year period. By "literacy", the NLM means not only learning how to read, write and count but also helping people understand why they are deprived and helping them move towards change.

Kanti is the niece of Suman.

Floods are the most frequent disaster in India, accounting for 52 per cent of the total occurrences of calamities, followed by cyclones (30 per cent), landslides (10 per cent), earthquakes (5 per cent) and droughts (2 per cent).

The question 'What specialities of Einstein impressed you the most and why?' is most appropriate to evaluate the thought process of a student as it takes into consideration student's thinking. This makes students to choose from among multiple answers and hence they could be engaged in thinking rationally. The answers that come out are also subjective, unlike the direct questions, which fail to evaluate the thought process of students.

• Waste is unusable material. Waste comes in many forms.
• Waste can be categorized as:
  • solid waste (vegetable peels, trash cans and other such municipal waste),
  • liquid waste (water discharge from industries, harmful runoff from fields etc),
  • and gaseous waste (harmful gases released from industries).

Key Points

Solid waste management is one important challenge of urban bodies. It can be achieved by following the 5 R's of waste management which are:

Refuse:

• Refuse the usage of non-biodegradable products as much as possible.
• Example: Refuse using plastic bags and using jute bags or cloth bags.

Reduce: 

• If users cannot be refused completely, reduce the amount of consumption.
• Example: Reducing the use of single-use plastics.

Reuse:

• As much as possible try to use a substance for as long as and in as many ways as possible.
• Example: Reuse wrapping paper, plastic bags, boxes.

Repurpose:

• For every item that can't be refused, reduced, or reused, try repurposing it.
• Example: try using wasted printer paper for scrap paper, cardboard boxes for storing supplies, binder clips to hold power cords

Recycle:  

• Recycling is the most environmentally friendly waste disposal method, which means collecting waste and produce a new product from it.
• Example: recycling of glass can be made to produce new glass jars and bottles or tiles.

Important Points

Plastic bags:

• A plastic bag should be avoided because it is harmful to the environment and is difficult to degrade.
• If one cannot avoid the use of plastic bags they must reuse, repurpose or recycle plastic bags.

​Thus, the incorrect match is Plastic bags: Landfill

Additional Information

Composting:

• Due to a lack of adequate space for landfills, biodegradable yard waste is allowed to decompose in a medium designed for the purpose.
• Only biodegradable waste materials are used in composting. Example: kitchen waste
• Good quality environmentally friendly manure is formed from the compost and can be used for agricultural purposes.
• It is the only sustainable means of waste disposal.​

Landfill:

• Landfill refers to the disposal of waste material by burying it.
• It is an extended storage area for non-biodegradable waste.
• Landfills may lead to contamination from the waste entering the area surrounding by soil and water and it also causes odour and pests.

A teacher work as a role model for students. A teacher is the best source of motivation. A teacher can guide the students to the right path and can make their future brighter. Above characteristics are important for a teacher and to be a motivator is the prime role and the duty of a teacher.

The Ministry of Environment, Forest, and Climate Change is the nodal Ministry for notifying the Environment Impact Assessment (EIA) Notification, under the Environment (Protection) Act, 1986. Section 3 of the Environment (Protection) Act 1986 (EPA), gives power to the central government to take all measures that it deems necessary or expedient for protecting and improving the quality of the environment, and preventing and controlling abating environmental pollution. So, statement 1 is correct.

• The EIA Notification seeks to reduce or even remove public participation, and by extension independent expert opinion, from the process of granting environmental clearances to various projects. The public reporting of the environmental violations may also not be taken cognizance of by the authorities. So, statement 2 is incorrect.
• Exemption from public consultation in certain projects - Section 14 of the Draft provides for exemption from public consultation, thereby limiting the scope of public involvement in districts. All offshore projects, located beyond 12 nautical miles are exempted. So, statement 3 is correct.
