Correct Answer: LOIR

Solution : Let's evaluate each option
First option: BYCX; B + 1 = C; Y – 1 = X

Third option: GTHS; G + 1 = H; T – 1 = S
Fourth option: LOIR; L – 3 = I; O + 3 = R

So, the fourth option is different from the other three options because the difference in the positional values of the letters is different. Hence, the fourth option is correct.

West Bengal annually yields 15-16 million tonnes of paddy across the three seasons: aus, aman and boro. The Kharif paddy, including aus and aman, constitutes approximately 70% of the total output. Boro paddy, cultivated on canal-dependent and irrigated land, makes up the rest. Aman, a rice variety, is sown during the rainy season and harvested in winter, primarily under rainfed lowland conditions with varying water levels, including shallow, semi-deep, deep and flooded conditions.

Correct Answer: Mr. Dey told the porter to put that suitcase in the first class compartment.

Solution : The correct choice is the second option.

Indirect speech conveys a report of something that was said or written rather than the exact words that were spoken or written.

In the conversion to indirect speech, the steps are as follows:

• The reporting verb "said" would be converted to "told".
• Rewrite the sentence (the actual word spoken) using the reporting verb, maintaining the imperative mood in the indirect speech.
• Change "this" to "that" to reflect the perspective of the listener.
• Include the recipient of the instruction, "the porter".

Therefore, the correct answer would be: "Mr. Dey told the porter to put that suitcase in the first-class compartment."

Correct Answer: c, b, d, f, e, a

Solution : Given:
a. Book b. Words c. Letters d. Sentences e. Chapters f. Pages

Books are fascinating objects that consist of various elements that work together to convey a message or tell a story. The most basic building blocks of a book are letters, which are combined to form words. Words, in turn, are strung together to make sentences, which are then written on a page. As more pages are added, they are grouped into chapters, and these chapters collectively make up a book. Ultimately, a book is a carefully crafted piece of literature that can educate, inspire, entertain, or enlighten readers.

So, the sequence is Letters, Words, Sentences, Pages, Chapters, Book or c, b, d, f, e, a. Hence, the fourth option is correct.

Correct Answer: (1)

Solution : The sentence can be improved using the first option.

The original sentence contains an incorrect use of the word vast. In this context, vast is not the appropriate word to describe the number of factors affecting job performance. One should use a number that means many to convey the idea of a significant or considerable number of factors.

Therefore, the correct sentence is: "Job performance is affected by a number of factors."
