- Explanation :
'Middle term should be distributed in at least one premise' is the only correct statement among those given. Categorical syllogisms have exactly three categorical propositions, two of which are premises; and the third is the conclusion. There are exactly three terms, each appearing only twice. Four rules apply to all valid categorical syllogism: Rule 1: The middle term must be distributed in at least one premise. Rule 2: Any term that is distributed in the conclusion must be distributed in the premises. Rule 3: The number of negative premises must be equal to the number of negative conclusions. Rule 4: No particular conclusion can be drawn from exclusively universal premises. Arguments that pass each of these tests are valid. Those that fail to satisfy even one of the rules are invalid
- Option : B
- Explanation : Technology enabled communication is most suited for uniform imparting of educative interactions. All such, it travels uniformly from the source and reaches every member of the audience regardless of their individual differences. Top down and linear communication style is suitable in organisations with multiple levels in hierarchy. Classroom teaching has ouly two levels-the teacher and the taught. Hierarchy in terms of performance levels is non-inclusive and undesirable in a class. Individual centric communication may challenge the teacher to ensure that every student in the class has received the information imparted, particularly when the class size is large. Individual differences among students would mean that some lag behind and fail to receive the communication. likewise, communication sel-projected by the teacher might fail to reach some students particularly when the class is large.
- Option : B
- Explanation : Stratified random sampling works best in case of a heterogeneous population. It is a method of sampling that involves the division of a population into smaller sub-groups known as strata, on the basis of the members' shared attributes or characteristics such as income or educational attainment. Simple random sampling is suitable to a homogenous population. It involves separate random selection of each household. Cluster sampling is simple random sample is taken from each of the different clusters in the population. Multiple clusters of people are created from a population where they are indicative of homogeneous characteristics and have an equal chance of being a part of the sample. Systematic random sampling does not involve separate random selection of each household. It is often used to select large samples from a long list of households and therefore, proceeds in a systematic manner, selecting every nth member of population to be included in the study.
- Option : A
- Explanation : The assertion, 'Classroom communication is pre-decided by social and institutional demands', is true. Classroom transaction at any class level is planned in accordance with the curriculum framework which lays down the guidelines for educational institutions about what to teach and how, in accordance with the Education Policy of the nation. The education policy is aims at educating its learner-citizens in keeping with the social demands of the nation. Institutions vary in the quality and level of resources, they make available for the teaching-learning process; so, institutional demands also influence and pre-decide classroom communication. The reason for this is that educative actions must be positively oriented and must also aim at positive outcomes so that learners acquire knowledge that is significant to fu1fil social demands. Hence, (R) is the correct reason for (A).
- Option : B
- Explanation : Total cost of 3 items at the rate of ₹1500 each = 3 x 1500 = ₹4500 Total cost of 2 items at the rate of ₹1800 each = 2 x 1800 = ₹3600 Total cost of 5 items = 4500 + 3600 = ₹8100 Discount = 10% Net cost = 8100 x (100-10)/100 = ₹7290 Average cost of the item = 7290/5 = ₹1458
