Question : 49 of 120

Marks: +1, -0

It is observed that to a problem like 'Show that the sum of any two odd numbers is an even number', most of the students replied by quoting one example, say, 5 + 7 = 12. Students answered this question inappropriately as

students have attained the formal operational stage as proposed by Piaget
students firmly believe that if a Statement is true for one set of numbers, it is always true and hence have developed strong strategy for making generalisations
students have not learnt the logical proof for the statement in the class
students have not understood that in Mathematics ‘any’ is used to indicate generalisations and hence are not able to answer correctly
