व्याकरण-अनुवाद विधि:

• किसी भाषा को सीखने की व्याकरण-अनुवाद विधि उसके व्याकरण के विस्तृत अध्ययन के माध्यम से होती है।
• इस विधि में, शिक्षार्थी पहले व्याकरणिक नियमों को सीखता है और फिर उन नियमों को लक्षित भाषा से मातृभाषा में वाक्यों का अनुवाद करने में लागू करता है।
• शिक्षार्थियों को व्याकरण के नियम सिखाने के लिए मुख्य रूप से मातृभाषा या मातृभाषा का प्रयोग किया जाता है ताकि अनुवाद आसान हो जाए।
• शब्दावली द्विभाषी शब्द सूचियों का उपयोग करके बनाई गई है, अर्थात मातृभाषा में और लक्ष्य भाषा में शब्दों के अर्थ को सिखाने के लिए।
• जब व्याकरण के नियमों को सीखने की बात आती है तो रटना या याद रखना एक महत्वपूर्ण भूमिका निभाता है।

इसलिए, व्याकरण-अनुवाद विधि का सिद्धांत व्याकरण के नियमों को याद रखना है।

A language item refers to a specific unit or element of language, such as a word, phrase, grammatical structure, or vocabulary item, that is taught or learned in language education and communication.

The statement "Children should be asked to do written work" will be the least important to the language teacher.
Language teachers create an environment that is conducive to learning in the following ways:

• Providing different kinds of material so that they can learn concepts with ease and efficiency.
• Using every possible area of the room to create an atmosphere that encourages participation and learning.
• Creating a positive atmosphere conducive to learning is to develop a positive classroom climate and culture. 
• Making children feel free to express themselves as it provides them the opportunities to communicate in context.
• Maintaining a neat and organized environment that is conducive to learning is getting the students to cooperate.
• Respecting learners' mother tongue so that it could promote the cognitive flexibilities to express the thought in multiple ways.

In linguistics, a compound is a lexeme (less precisely, a word) that consists of more than one stem. Compounding, composition or nominal composition is the process of word formation that creates compound lexemes. That is, in familiar terms, compounding occurs when two or more words are joined to make one longer word. There are three forms of compound words:
The closed form, in which the words are melded together, such as firefly, secondhand, softball, childlike, crosstown, redhead, keyboard, makeup, notebook;
The hyphenated form, such as daughter-in-law, master-at-arms, over-the-counter, six-pack, six-year-old, mass-produced; and The open form, such as post office, real estate, middle class, full moon, half sister, attorney general.
Blending: A blend is a word formed by joining parts of two words after clipping. An example is 'smog', which comes from 'smoke' and 'fog', or 'brunch', which comes from 'breakfast' and 'lunch'.

Here, we need comparative form of adjective. Option (1) is incorrect as it uses double comparatives.

• Together: in or into one place, mass, collection, or group
  Example: Our students study together, share ideas, and seed new opportunities for future collaboration.
• Solely: without another
  Example: You will be held solely responsible for any damage.

​Thus, "solely" is the most opposite in meaning to "together".

While learning a language, the programmed instruction provides opportunities for independent study, a wide range of reference material and an immediate feedback about achievement.
Programmed instruction is a method of presenting new subject matter to students in a graded sequence of controlled steps. Students work through the programmed material by themselves at their own speed and after each step, test their comprehension by answering an examination question or filling in a diagram.

Given:
∠ABC = 90° and ∠DCB = 90°
AB = DC (given)
Calculation:
AB = DC (given)
∠ABC = ∠DCB = 90° 
BC = BC (Since the line segment BC is common to both triangles)
By the SAS Congruence Property,  ΔABC ≅ ΔDCB

A homologous series is a series of compounds with the same general formula, usually varying by a single parameter—such as the length of a carbon chain.
In the above correct option, CH₂ units are added (Straight-chain Alkanes).

Given:
One dice shows a multiple of 2.
Other dice show the odd number.
Concept used:
The total number of outcomes when two dice are thrown is 36.
Formula used:
P = Favorable outcomes/Total outcomes 
Calculation:
The number of favourable outcomes is 9
(2,1), (2,3) (2,5) (4,1) (4,3) (4,5) (6,1) (6,3) (6,5)
Required probability = 9/36 = 1/4
∴ The probability is 1/4.

Non-metallic oxides dissolve in H₂O to give acidic solution which turns blue litmus red. Therefore, the correct answer is CO₂.

When ozone levels decrease below 200 DU, the condition generally qualifies as an ozone hole. The ozone hole is not technically a hole where no ozone is present, but is actually a region of exceptionally depleted ozone in the stratosphere over the Antarctic that happens at the beginning of Southern Hemisphere spring (August–October).

A concept map provides a concrete record of the connections perceived by the students, and thus it indicates how the student’s knowledge is organized and interconnected. Mapping is the creative process of organizing content and can be used in planning lessons, learning, and developing mathematical literacy and spatial thinking.

• Most nonmetals do not react with air at room temperature.
• But, White phosphorus is the only nonmetal that reacts with air to form its oxide by burning.
• Phosphorus is a non-metallic element.
• White phosphorus is the form that occurs most commonly at room temperature.
• It is very reactive and combines with oxygen in the air very easily.
• It catches fire spontaneously when exposed to air.
• In chemical laboratories, it is stored underwater to avoid burning.

Scientific Processes:  All processes in science are done with specific purpose, evidences are collected with reliable and valid methods, and they are examined critically by controlling different variables.

Option (4) is the correct option because with a process approach, the curriculum development itself becomes an intervention, which may have an impact upon individuals as well as on organisations and institutions.

A teaching method is an orderly and logical arrangement of ideas based on a particular approach. It is a procedural illustration of systematic and clearly defined steps for accomplishing particular objectives.

While formulating objectives of science, one must keep the following factors in mind:
(i) The need and capabilities of the learner: This is an important factor, as the end consumers are the students. The teacher needs to have a fair understanding of the capabilities of his/her students, so that she can teach them on the basis of their previous knowledge. She must be able to link their already existing knowledge, to provide them a better understanding of the topic being taught. Besides, the needs of the students must be kept in mind. A student of class VI cannot be taught a topic in the same way as it has to be taught to a class X student.
(ii) The nature of the highest subject matter: The teacher must draw a line on what must be taught to students at a particular stage. The books become a valuable resource for the same, as they draw out a basic plan for the teacher.
The capability of the subject teacher is not one of the factors. The teacher must have enough capability to teach the subject matter, as per the objectives framed. In case she feels it is above her capacity, she must take the help of other teachers, but should not compromise on what the students are being taught.

B. S. Bloom's taxonomy of learning, educational, and instructional objectives into the following three domains is in a proper hierarchy.

• Cognitive domain: Those educational objectives are included that are concerned with knowledge, recognition, recall and cater to the development of intellectual abilities and skills.
• Affective domain: The objectives which are related to the domain of interests, attitudes, and values bring about desirable changes in the same included in this domain. 
• Conative or psychomotor domain: ​This domain helps in the development of skills. The training of physical activities is the main objective of this domain.
