Question 8

Ayyankali's historic journey in a 'villuvandi' (bullock cart) through public roads, traditionally forbidden to lower castes, was a powerful act of defiance.

Accepted Answer

B. To demonstrate the right to public space and challenge the physical manifestation of caste discrimination. — Ayyankali's 'villuvandi' protest was a direct action aimed at asserting the fundamental right of depressed classes to use public roads, which were symbols of upper-caste dominance.

While legislative representation (A) and land reforms (C) were important issues, they were not the immediate goal of this specific act. Mass conversions (D) were not Ayyankali's primary method, as he focused more on asserting rights within the existing social fabric.

Question 10

A teacher administers a unit test after completing a chapter on 'Photosynthesis' to determine if students have understood the concepts before moving to the next chapter. Based on the results, she plans to conduct a remedial class for weaker students. This unit test functions primarily as what type of assessment?

Accepted Answer

B. Formative assessment — Although it's called a 'unit test,' its purpose here is to inform instruction and provide feedback for remedial action *before* moving on, indicating its role in guiding ongoing learning and teaching adjustments. This aligns with the definition of formative assessment. If it were solely for assigning a final grade at the end of a larger instructional period, it would be summative. Diagnostic assessment occurs *before* instruction begins to identify prior knowledge, and achievement assessment is a broader term often encompassing summative evaluation.

Answer

A. Diagnostic assessment

Answer

C. Summative assessment

Answer

D. Achievement assessment
