No indicated and two distinct valid reasons based on sample size/time/location/bias. e.g. ‘She needs to ask more than 15 people’. ‘She needs to vary the time that she asks people, not just go to one meeting’. ‘People at the drama group will probably go more often’.	E2	No may be clearly implied by two valid reasons without contradiction. E1 for either: one valid reason, two valid reasons, but with Yes indicated. Allow E2 if two reasons are stated in one answer space, with the second answer space blank or containing a non-contradictory reason. Allow ‘she’s only asking 15 people’, ‘she’s only asking people in her drama group’, ‘maybe not everyone in her drama group is from her town’. Do not allow ‘she hasn’t asked everyone in her town’.
