P: People celebrate it as a two-day festival; first day as Holika Daha
Q: Holi is a religious Hindu festival celebrated with lots of preparations in the month of Phalgun.
R: At Holika Dahan, they burn a heap of sticks, straws and cow-dung cakes lying in the mid of streets in the late evening or night.
S: And, next day in the morning, they celebrate a colorful Holi by playing colours with friends, family members and neighbours.
Right Answer is: A
Since the passage is about the festival of Holi, Q must be the first sentence as it introduces it. P must follow next as the pronoun “it” refers to the festival of Holi introduced in Q. R and S should be the last two sentences as R mentions the first day, while S mentions the second. Thus, the sequence after rearrangement is QPRS, and option A is the correct answer.
