Correct Answer: he : 8

Solution : Given:
1. you must study ⇒ 531
2. he must work ⇒ 718
3. work is worship ⇒ 894
4. work is fine ⇒ 864

By comparing all the above-coded sentences, we find that –
In sentences 1 and 2, must is a common word and 1 is a common code.
In sentences 2, 3, and 4, work is a common word and 8 is a common code.
In sentences 3 and 4, is is a common word and 4 is a common code.

So, the word and code in the above sentences –
must→1; work→8; is→4; you/study→5/3; he→7; worship→9; fine→6

So, he: 8 is NOT a correct combination of a word and its code in that language. Hence, the third option is correct.

Correct Answer: To slowly starve the boys to death

Solution : The correct option is the second option.

Explanation:
The passage describes the decision made by the board (the gentlemen) regarding the treatment of the poor in the workhouse. They believed the workhouse was a place of leisure and decided to stop what they perceived as excessive entertainment. Their solution was to implement a rule that all poor people should be starved gradually in the house. They arranged for minimal, insufficient meals—three meals of thin gruel a day, with an onion twice a week, and half a roll of bread on Sundays—intending to gradually reduce the food intake to the point of starvation. This decision was cruel and aimed at depriving the poor of adequate sustenance rather than providing for their needs.

Therefore, the correct answer would be, to slowly starve the boys to death.
