If (R) is transitive and ((p,q)\in R), ((q,r)\in R), ((r,s)\in R), which listed pair must definitely be in (R)?

Answer and explanation

Correct answer: ((p,r))

Step 1: First connect ((p,q)) and ((q,r)). Step 2: By transitivity, ((p,r)) must be in (R). Further pairs like ((q,s)) and ((p,s)) may also follow, but ((p,r)) is listed. Step 3: In a long chain, begin with two adjacent pairs.
