Option A states that expertise changes when "the social context" changes. What is the social context referred to here? It could apply equally well to the context mentioned in B (a different team with many other exceptional players) or to the one mentioned in D (a network of high performing athletes and support staff). So, both AB and AD make sense. Now, looking at C, we see that this only fits with AD and not AB. Both C and D talk of the importance of support staff in team sports. ACD makes a cogent paragraph. So, B is the odd one out. Correct Answer: Choice (B)
