JUSTIFICATION OF DISTRACTORS QUESTION 3 Option 1

Justification Correct answer. Pupils may select this option as both the absorption of water and minerals and the holding and supporting of the plant are functions of roots of plants that are planted in soil.

2

However, the plant in this question is water hyacinth, which do not grow in soil but floats on water. Hence, its roots do not help to hold and support the plant firmly. Pupils who select this option shows that they have the knowledge and understanding of the functions of roots of plants grown in soil, but they are not able to apply the concept these understanding to a new situation. Pupils may select this option as they think that water hyacinth, being partially submerged in water, grows/lives in the

3

same manner as fishes. Hence, they may decide that, like fishes, plants that floats on water also absorbs the dissolved oxygen present in the water. Pupils may arrive at this option by elimination method.

4

Firstly, pupils may think that since water hyacinth is already partially submerged in water, it does not need to take in any more water from its roots. Hence, statement A would be eliminated, and they would then arrive at Option 4.

QUESTION 5 Option 1

Justification Correct answer. Pupils may select this option if they are unaware that there is a difference in strength of attraction at different points

2

of a magnet. Hence, they may think that the number of paper clips attracted will be random and not follow any particular pattern. Only this option provides a random number of paper clips attracted at the 4 points. Pupils may select this option as they think that the strength of attraction of a bar magnet is the same at any point of

3

the magnet. They may think that since the bar magnet was lowered horizontally onto the pile of metal paper clips, the number of paper clips should be the same at every point. These pupils have not shown understanding that the two poles of a magnet display the strongest force of attraction. Pupils may select this option if their knowledge of this concept is unclear. They most likely have knowledge that the

4

strength of attraction is strongest at certain points of the magnet, but are unable to identify that it is the 2 poles. Also, pupils may select this option if they do not have knowledge of where the poles of the bar magnet is at, and hence are unable to select the right option.
