Solution:

If yesterday was Sunday, and we're counting forward to find the 81st day from today, we can start by noting that 81 days is equivalent to 11×7+4 days.

Counting the weeks: If today is Monday, after 11 weeks (which each end on the same weekday), it would still be Monday.

Adding the extra 4 days: Starting from Monday:

Monday + 1 day = Tuesday
Tuesday + 1 day = Wednesday
Wednesday + 1 day = Thursday
Thursday + 1 day = Friday
Thus, the 81st day from today is Friday

Hence, the answer is:

Friday

Q8.Five jumbled up sentences, related to a topic, are given below. Four of them can be put together to form a coherent paragraph.

Q9.The passage given below is followed by four alternate summaries. Choose the option that best captures the essence of the passage. Aesthetic political representation urges us to realize that ‘the representative has autonomy with regard to the people represented’ but autonomy then is not an excuse to abandon one’s responsibility. Aesthetic autonomy requires cultivation of ‘disinterestedness’ on the part of actors which is not indifference. To have disinterestedness, that is, to have comportment towards the beautiful that is devoid of all ulterior references to use – requires a kind of aesthetic commitment; it is the liberation of ourselves for the release of what has proper worth only in itself.

Complex computational elements of the CNS are organized according to a “nested” hierarchic criterion; the organization is not permanent and can change dynamically from moment to moment as they carry out a computational task. 2. Echolocation in bats exemplifies adaptation produced by natural selection; a function not produced by natural selection for its current use is exaptation -- feathers might have originally arisen in the context of selection for insulation. 3. From a structural standpoint, consistent with exaptation, the living organism is organized as a complex of “Russian Matryoshka Dolls” -- smaller structures are contained within larger ones in multiple layers. 4.
