Statement 1: Mangoes can be plucked from the trees but the grain seeds of plants like maize cannot be plucked from their stalks.
Statement 2: Grain seeds of maize are very much bigger in size as compared to their stalks.
Statement 1 is true but statement 2 is false.
One may pluck mangoes or guavas from the trees. But, grain seeds are much smaller than mangoes or guavas. By using the method of hand picking, it will be very difficult and will take a very long time. So, plucking them from their stalks would be impractical and time-consuming. Hence, statement 1 is true but statement 2 is false.
