Ocean currents are set in motion primarily by prevailing winds<br>4. Ocean current are affected by the configuration of the ocean

Correct Answer: 2, 3 and 4
The Ocean currents are not only slow but also could be fast, so 2, 3 and 4 statements are correct.

Which of these statements are correct?
1. Ocean currents are the slow- surface movement of water in the ocean.
2. Ocean currents assist in maintaining the Earth's heat balance.
3. Ocean currents are set in motion primarily by prevailing winds.
4. Ocean currents are affected by the configuration of the ocean.

With reference to Ocean currents consider the following statements:
1. West Australian current is a warm current.
2. North East Monsoon Drift flows in the Indian Ocean during winter season.
3. Equatorial counter current does not flow in the Indian Ocean during winter season.
4. Kuroshic current in the Pacific Ocean is like Gulf Stream in the Atlantic Ocean.

Suppose on performing reduced error pruning, we collapsed a node and observed an improvement in the prediction accuracy on the validation set. Which among the following statements are possible in light of the performance improvement observed? (a) The collapsed node helped overcome the effect of one or more noise affected data points in the training set (b) The validation set had one or more noise affected data points in the region corresponding to the collapsed node (c) The validation set did not have any data points along at least one of the collapsed branches (d) The validation set did have data points adversely affected by the collapsed node

In the following question, two statements are given each followed by two conclusions I and II. You have to consider the statements to be true even ifthey seem to be at variance from commonly known facts. You have to decide which of the given conclusions, if any, follows from the given statements. Statements:
(I) Empty set is a subset of any set.
(II) A set is a subset of power set. Conclusion:
(I) Empty set is a power set.
(II) A set is a subset of power set.
