HTET PRT Mock Test - 9 - HTET MCQ

The early life of a child from birth to the age of two years is called infancy. Parents play a very vital role in the growth and development of a child during this period.

First generation learners are defined as students whose parent(s)/legal guardian(s) has/have not completed any formal schooling. This means that they are the first in their family to attend school. Generally, there is no one at home to encourage such children for self-studying. So, option 2 is the correct answer.

Active Participation means when children initiate to speak something when they try to participate in group discussions. The teachers force children so that they will try to be good speakers and gain confidence.
Hence, the correct answer is "Active participation".

While storytelling, a teacher maintains a natural sequence so that children take more interest in the class. The nature of human beings is that they take more interest in realistic things. Characters of the story should be properly elaborated so that while listening to the story it will easily be understandable by others. 
Hence, the correct answer is "All of the above".

Cognitive characteristics are the mental processes that are involved in acquiring, processing, and storing information. These processes can vary greatly from person to person, and they can also change over time as a result of experience, learning, and development.

Teachers are the most important resources in educational settings. They are the key figures for any changes required in the educational field. Their patience and perseverance significantly impact a student's success in the classroom.

सही उत्तर "शाबाश" है।

• दिए गए विकल्पों में, 'शाबाश' शब्द 'विस्मयादिबोधक' अव्यय है।
• दिए गए जिन शब्दों से शोक, विस्मय, घृणा, आश्चर्य आदि भाव व्यक्त हों, उन्हें विस्मयादि बोधक अव्यय कहा जाता है।
• जैसे - (शाबाश!) तुमने बहुत अच्छा कार्य किया।
• इस वाक्य में आश्चर्य के भाव प्रकट हों रहा है और साथ ही इस वाक्य में विस्मयादिबोधक (!) चिह्न का प्रयोग हुआ है इसलिए यहां विस्मयसूचक अव्यय है।

Key Points

अन्य विकल्पों का विश्लेषण:

Additional Information

• वे शब्द जिनमे लिंग, कारक, वचन, पुरुष आदि के कारण कोई विकार/ परिवर्तन उत्पन्न नहीं होता है, अव्यय शब्द कहलाते है।
• जैसे – आज, कब, इधर, किन्तु आदि।
• अव्यय के पांच भेद हैं –

सही उत्तर 'कार मत तेज मत चलाओ।' है।

• 'कार मत तेज मत चलाओ।' वाक्य में 'मत' (आज्ञा के लिए) का प्रयोग अशुद्ध और अनुचित है।
• शुद्ध वाक्य: कार तेज मत चलाओ।
• उपरोक्त वाक्य में 'मत' शब्द का प्रयोग दो बार हुआ है जिसके कारण वाक्य का अर्थ स्पष्ट नहीं हो रहा है।

Key Points

• वाक्य अशुद्धि शोधन- ‘वाक्य’ भाषा की महत्त्वपूर्ण इकाई है,अत: वाक्य को बोलते व लिखते समय उसकी शुद्धता, स्पष्टता और सार्थकता का ध्यान रखना आवश्यक है।
• यदि वाक्य में किसी तरह की अशुद्धि होती है तो आपके बोले गए वाक्य अर्थ भी बदल सकता है। सामने वाले व्यक्ति को आसानी से और सही-सही समझ आ सके उसके लिए आवश्यक है कि व्याकरण के नियमों की दृष्टि से ‘वाक्य’ को शुद्ध हो।
• अत: वाक्य को व्याकरण के नियमों के अनुसार शुद्ध करना ही ‘वाक्य अशुद्धि शोधन’ कहलाता है।

Leave in the lurch: to leave in an uncomfortable or desperate situation; desert in time of trouble.
Cut corners: do something perfunctorily so as to save time or money.
Leave hanging: keep undecided, uncertain, or in suspense.
Above board: legitimate, honest, and open.
Hence, the correct answer is option C. 

Get one’s head around: to understand, comprehend, apprehend, grasp, discern, recognize, interpret, get to know, fathom, get to the bottom of, come to terms with. This idiom can fit in the blank as the sentence implies that the concept is a little hard to understand.
Cry over spilt milk: regret of something that you will never be able to change. This idiom does not fit in the blank as there cannot be regret due to a concept.
Give a wide birth: stay away from (someone or something).
Hence, the correct answer is option C. 

As per the given above sentence is given in Passive Voice.
Use structure “To + subject( object ) + auxiliary + past participle”
To resign was his obligation.
Therefore ,required answer will be option B .

The passive voice of imperative sentences which suggest order, suggestion or request can be made in two ways:

Active: Verb + object

Passive:

Let + object + be + past participle
You are requested/ ordered/ suggested + to + verb (Ist form) + object
Going by first way of passive voice, the passive voice of the given sentence would be: Let the door be shut.

• Meaning of Quarantine: To separate someone into isolation.
• Meaning of Rescue: save (someone) from a dangerous or difficult situation
• Meaning of Detention: the action of detaining someone or the state of being detained in official custody
• Meaning of Defence: the action of defending from or resisting an attack

One side by car = 5 – 4 = 1 hour
So the answer = 1 × 2 = 2 hours
Hence, Option B is correct.

As chalk is used to write on the blackboard similarly the Ink is used to write on the paper.

These are all defensive games.

From the given open cube we will find the opposite pairs as shown-

Here, A is opposite to C, B is opposite to H, 9 is opposite to D. 

Now, these opposite pairs can NOT be together by seeing from one side if they are together → that cube can not be made.

Here, Image (II)  has opposite pair B and H together → This cube can not be made.

Image (IV)  has opposite pair A and C together → This cube can not be made.

Hence, Option (2) is correct.

 Additional Information

• Dices are of two types :

1.  Standard Dice
2. Non-Standard Dice.

• Dice has:-

1. faces = 6
2. sides = 12
3. corners = 8

• Two opposite faces never seen together.
• Adjacent faces are never opposite to each other.

On observing the given figures carefully, we get:

In the question figure,

1. One dot is in the common area of one square and one circle.

2. One dot is in the common area of one triangle and one circle.

Option (2) → All the required conditions are fulfilled as shown below:

Option (1) → Common area of triangle and circle not present.

Option (3) → Common area of triangle and circle not present.

Figure (4) → Common area of triangle and circle not present.

Hence, the correct answer is "Option (2)".

Important Points  

We should not think of the exact shape and size of the figures in these questions.

Just resemblance will work like if an Equilateral triangle is given in the question figure, any shape of a triangle in the answer figure will work, be it right triangle or scalene triangle.

Time → A : C = 40 : 90 = 4 : 9
Efficiency → A : C = 9 : 4

Hence, Option D is correct.

Base and height of ΔABF and ΔCED are same. Thus their respective areas will be same.

Total area = (Area of △ABF)×2+Area of rectangle BCEF 

Total area = (1/2×10×6)×2+(10×20) = 60+200

Total area = 260cm²

The correct answer is ​0 to 14.

Important Points

• The pH scale is the scale used to express the acidity or alkalinity of a substance based on the concentration of hydrogen ions in its solution.
  • pH scale was discovered by Soren Sorensen.
  • The range of pH scale 0 to 14.
    • If pH < 7 then solution is acidic.
    • If pH > 7 then solution is basic.
    • If pH = 7 then solution is neutral.

Additional Information

• pH means the potential of Hydrogen.
• The strength of acids and bases depends on the number of H⁺ ions and OH^- ions produced, respectively.
• The human body works within the pH range of 7.0 to 7.8.
• When the pH of rainwater is less than 5.6, it is called acid rain.
• Tooth decay starts when the pH of the mouth is lower than 5.5.

• Waste produced in the health care sector can prove highly hazardous, more so in the pandemic era.
• Biomedical waste is any waste containing infectious or potentially infectious materials.
• These wastes are generated during the diagnosis, treatment, and immunization of humans and animals.
• Biomedical wastes can be in both solid and liquid forms. Examples of biomedical wastes include:
• Waste sharps such as needles, lancets, syringes, scalpels, and broken glass
• Human tissues or identifiable body parts (as a result of amputation)
• Animal tissues and waste from veterinary hospitals, Used bandages, dressings, gloves, and other medical supplies
• Liquid waste from infected areas, Laboratory wastes

Biomedical wastes are distinct from regular garbage and require particular disposal and treatment.

Important Points 

The World Health Organization (WHO) has categorized biomedical waste into eight categories. They are:

• Infectious Waste – Any biomedical waste that is infectious or contaminated.
• Sharps – Sharps objects like needles, scalpels, broken glass, and razors.
• Pathological Waste – Body parts of humans or animals, including tissues, fluids, or blood.
• Pharmaceutical Waste – Unused drugs, medicine, or creams that are expiring.
• Genotoxic Waste – Toxic drugs and hazardous toxic waste
• Radioactive Waste – Any waste containing potentially radioactive materials
• Chemical Waste – Liquid waste from machines, batteries, and disinfectants is chemical.
• General/Other Waste – All other non-hazardous waste.

Additional Information

Color-coded bins to dispose of biomedical wastes:

Yellow Bin: For anatomical waste, chemical waste, soiled waste, chemotherapy waste, discarded linen and medicines, and laboratory waste.
Red Bin: For contaminated solid waste like infected dressings, and pop casts.
Blue Bin(Infected plastic): Syringes, gloves & cut glasses
Black Bin: For hazardous and other waste

White Bin: (Sharps) Needles & cut glasses

• Pollution is any undesirable change in physical, chemical, or biological characteristics of air, land, water, or soil.
• Agents that bring about such an undesirable change are called pollutants.
• Pollution can be broadly classified into 4 types - Air pollution, Water pollution, Noise pollution & Soil pollution.

Important Points

• Water pollution occurs when there is an addition of undesirable substances into water bodies.
• The sources of water pollution can be divided into 2 major groups:
  • Point source - It refers to the single identifiable sources like discharge pipes from a factory or sewage plant.
  • Non-point source - It refers to sources that do not originate from a single point. Example - agricultural run-offs.
• Factories and sewage treatment plants have proper drainage pipes leading to a water body for disposing their wastes and thus they are point sources of water pollution.
• Urban and Suburban lands cause water pollution by the field run offs and thus do not originate from a single point. Hence, they are non-point sources of water pollution.

The correct answer is All of the above.

• Air pollutants are mainly classified as primary and secondary.
• The pollutants which emit directly into the atmosphere and remain in the same chemical form are known as primary pollutants.
• The pollutants which undergo chemical changes in the atmosphere due to the reaction of two or more pollutants are known as secondary pollutants.
• Pollutants like sulphur dioxide, nitrogen dioxide, particulates fall under the category of primary pollutants.

Additional Information

The correct answer is Ethanol + Methanol​.

• Ethanol + Methanol​ is denatured alcohol.
• Denatured alcohol is ethanol that has additives to make it poisonous, bad-tasting, foul-smelling, or nauseating to discourage its recreational consumption.
• The term denatured alcohol refers to alcohol products adulterated with toxic and/or bad tasting additives (e.g., methanol, benzene, pyridine, castor oil, gasoline, isopropyl alcohol, and acetone), making it unsuitable for human consumption.
• The most common additive used is methanol (5–10%), giving rise to the term methylated spirits. Denatured alcohol is used as a lower-cost solvent or fuel for home-scale or industrial use.

Key Points

• Denatured alcohol is ethanol or grain alcohol that contains additional chemicals called denaturants that make it unfit for human consumption.
• Denatured alcohol is fine for some types of lab work and as an ingredient in certain products, but it's not safe to drink.
• Ethanol is an organic chemical compound. It is simple alcohol with the chemical formula C₂H₆O.
• Its formula can be also written as CH₃−CH₂−OH or C₂H₅OH and is often abbreviated as EtOH.

Additional Information

• Alcohol (ethanol or ethyl alcohol) is the ingredient found in beer, wine, and spirits that causes drunkenness.
• Alcohol is formed when yeast ferments (breaks down without oxygen) the sugars in different food. 

The correct answer is Option(2).i.e.Alpha Decay.     

• In radioactivity, the emission consists of the Helium nucleus sustains under Alpha Decay. 
• Alpha Decay: 
  • It is basically responsible for the emission of the Helium nucleus. 
  • An alpha particle is consists of two neutrons & two protons which is the same as a helium nucleus.
  • We generally use 24He to implement an alpha particle which has a 2+ charge.
  • The original atomic number of the atom decreases by two (because of the loss of two protons), and its mass number decreases by four (because of the loss of four nuclear particles) when a radioactive atom throws down an alpha particle. 
• Emission of Alpha Particle: 
  •  The emission of an alpha particle can be present with a chemical equation: 
  • For example, the alpha-particle emission of uranium-235 is as follows:
       ²³⁵U₉₂→⁴He₂ + ²³¹Th₉₀  

Key-Points

Water Pollution:

• Water pollution occurs when harmful substances often chemicals or microorganisms contaminate a stream, river, lake, ocean, aquifer, or other body of water, degrading water quality and rendering it toxic to humans or the environment.
• Water pollution is a major environmental issue in India.
• The largest source of water pollution in India is untreated sewage.
• Other sources of pollution include agricultural runoff and unregulated small-scale industry.
• Most rivers, lakes, and surface water in India are polluted due to industries, untreated sewage, and solid wastes.

Hence, option 1 is the correct answer. 

Important Points
​Untreated Sewage:

• A 2007 study found that the discharge of untreated sewage is the single most important source of pollution of surface and groundwater in India.
• There is a large gap between the generation and treatment of domestic wastewater in India.
• The problem is not only that India lacks sufficient treatment capacity but also that the sewage treatment plants that exist do not operate and are not maintained.

Additional Information

1. Agriculture run-off: Farms discharge large quantities of agrochemicals, organic matter, drug residues, sediments, and saline drainage into water bodies. Nevertheless, agricultural pollution, aggravated by increased sediment runoff and groundwater salinization, is also becoming an issue.
2. Unregulated small-scale industries and religious practices comparatively have less contribution to water pollution in major rivers of India.

The correct answer is option 3, i.e. Solid solution.

Alloy is an example of a solid solution.

• Alloy is the fusion or mixing of two or more metals and metals with non-metals.
  • Example of an alloy is Brass that is a mixture of copper and zinc.
  • The property of the resulting mixture differs from pure metals. For example, increasing hardness.
  • An alloy retains all the property of metal-like electrical conductivity, ductility, lustre etc.
  • Alloys are used in applications like building, automobiles, surgical tools and aerospace industry etc.
• A colloidal solution is a mixture in which substances are regularly suspended in the fluid. For example, plaster, paper, milk, gelatine, jelly etc.
• The emulsion is a mixture of two or more liquids which are not soluble. For example egg yolk, butter.
• A heterogeneous mixture is a mixture of non-uniform composition. The mixture of two or more phases is called a heterogeneous mixture. For example, ice cubes in a drink, oil and water, salt and oil etc.
