The following situations involve a cluster of three or more geometrical figures. Having one or more dots placed at nay point inside the cluster. This cluster is followed by a set of four altenative figures each composed of a cluster of the same type of figures. Now. For each dot we have to observe the region in which it is enclosed i.e in Which of the geometrical figure this region is common. From amongst the figures, select the figure which satisfies the same conditions of placement of the dot as in fig. (x)
