Which of the following is the last (seventh) sentence of the paragraph after rearrangement?

Seven statements are given below, which are jumbled in any random order. Only the first statement (a) and the sixth statement (f), which have been emboldened, are in their correct places. These statements will form a coherent and meaningful paragraph, when arranged in the correct sequence. Arrange the sentences in the right order and answer the questions that follow. (a) Imagine a Zoom session on pure mathematics by college professors being interspersed every now and again with a raucous recital of the first ten numbers by kindergarteners. (b) Tower Twisters, a chapter of Chennai Runners, spotted a similar mismatch with the result that it now operates with four official WhatsApp groups. (c) This group countenances these digressions, as almost everyone is guilty of them at some point. (d) The group has a low tolerance threshold for any attempts to get a non-running line in, straight or edgeways. (e) Though both exercises deal with maths, throwing them together is an incongruity. (f) There is another for members who are serious about running, but simply cannot resist the temptation of running through every topic at hand, chatting away to glory. (g) Vikram Mohan, one of Tower Twisters’ founding-members, notes that one WhatsApp group hosts those members with a blinkered vision, being fixated only on running.
