Hi
For mcq questions,Try to identify the topic the question is tested and the concept in one minute or less.Once you find these,it will take a few seconds to finish the answer.
Take question 1 for example.

Q1.Topic:Web of life.Concept:Interdependency in animals
Answer is (1) since aphids are eaten by lady birds which is true.Aphids is not eaten by frog.
Try this method for the other three questions.All the best for your PSLE.
Cheers

Answer is 3, because the table top is parallel to the ground.

Gravity only needs to be overcome (in order to move) when the surface is tilted and the object is traveling against gravity (upwards).

Thanks mamago. One more question. What is the direction of the magnetic force between the steel table top and magnet?
