Researcher: We conducted an experiment where we asked people to each build the same simple model. We enlisted 200 volunteers and randomly divided them into 4 groups (Groups 1–4) of 50 members each. Each volunteer was assigned to exactly one of the groups. Each member of Group 1 was given as much time as that member needed to build the model. Each member of Group 2 was given a limited amount of time in which to build the model. Each member of Group 3 was asked to build the model while wearing a blindfold, and was given as much time as needed. Each member of Group 4 was asked to build the model while wearing a blindfold, and was given a limited amount of time. The researchers found that 98% of Group 1, 46% of Group 2, 90% of Group 3, and 20% of Group 4 were able to successfully build the model.

1)B,since if see the four groups success %
a)Group A -No blindfold, sufficient time-98%
b)Group B -No blindfold, limited time-46%
c)Group C - blindfold, sufficient time-90%
d)Group D - blindfold, limited time-20%
So here we see that the major transition in the success % is from the sufficient time to limited time,while the change from no blindfold to blindfold is only 8% ,while the time shows a greater % change, hence becomimg the key player here.
2)Presence of blindfold had a significant change as seen from the above answer's analysis

The four groups success %
a)Group 1 -No blindfold, sufficient time-98%
b)Group 2 -No blindfold, limited time-46%
c)Group 3 - blindfold, sufficient time-90%
d)Group 4 - blindfold, limited time-20%
From the above analysis, it is clear that when given unlimited amount of time(sufficient time/no time constraints) the success percentages are in the higher range of 90% for Group 3 and 98 % for Group 1 respectively. Thus it is a significant factor.
For blindfold the success ratio for Group 2 and Group 4 are 46% and 20% respectively, thus no major effect due to this, Hence not a significant factor.
Answer will be B, A.
Note that the other factors mentioned in the question like group size are out of the scope.
a)Group 1 -No blindfold, sufficient time-98%
b)Group 2 -No blindfold, limited time-46%
c)Group 3 - blindfold, sufficient time-90%
d)Group 4 - blindfold, limited time-20%
