Each of the next items consist of two statements, one labeled as the Statement (I) and the other as Statement (II). You are to examine these two statements carefully and select the answers to these items using the codes given below:

1 Both Statement (I) and Statement (II) are individually true and Statement (II) is the correct explanation of Statement (I

2 Both Statement (I) and Statement (II) are individually true but Statement (II) is NOT the correct explanation of Statement (I)

3 Statement (I) is true but Statement (II) is false

4 Statement (I) is false but Statement (II) is true
