32. Which one of the following factors does not contribute to learning mathematical concepts
- Option : C
- Explanation : Mathematics has been accepted as an importance component of formal education from ancient period to the present day. Most of respondents and instructors agreed that demographic, instructional strategies and methods and individual factors are the most influential factors in learning mathematics. According to 'Underhill' beliefs in mathematics is the summary of four beliefs, namely (i) beliefs in Mathematics as a discipline, (ii) beliefs in learning Mathematics, (iii) beliefs in teaching Mathematics, and (iv) beliefs in one self in the context where Mathematics learning occurs. Thus teaching mathematics with any subject like history or other does not contribute to learning mathematical concepts.
- Option : D
- Explanation : Creativity is stimulated if team members avoid consensus and challenge each other; however, criticism and conflict among team members can hinder creativity. If team members respect one another, they will think without fear of being ridiculed; otherwise, they may be unwilling to share vital knowledge and skills.
- Option : D
- Explanation : In the stratosphere, ozone molecules absorb ultraviolet radiation from the Sun and shield Earth from dangerous rays. But in the troposphere, near ground-level, ozone molecules are both air pollutants, threatening the health of living things, and greenhouse gases, trapping heat and contributing to climate change. The highest ozone concentrations of the year generally occur during summer, when sunlight is most intense. Ozone concentrations consequently reach maximum shortly after the peak in vehicle traffic, about noon or soon thereafter. So, (A) is false. However, (R) is true; the atmosphere is most unstable during the afternoon because heating of the earth's surface heats up the air just above it which expands and its components get diluted.
- Option : D
- Explanation : If a term of a categorical proposition refers to every member of a class, it is said to be distributed; if the term is not being used to refer to each and every member of the class, it is undistributed. As shown in the following table, the given proposition is I type, particular affirmative, where the subject as well as the predicate is undistributed
Type Form Quantity Quality Distribution Subject Predicate A AIl S is P universal affirmative distributed undistributed E No S is P universal negative distributed distributed I Some S is P particular affirmative undistributed undistributed O Some S is not P particular negative undistributed distributed
