A common hydrometer reads specific gravity of liquids. Compared to the 1.6 mark of the stem, the mark 1.5 will be
1 upwards
2 downwards
3 in the same place
4 may be upward or downward depending upon the hydrometer
Explanation:
In hydrometer, lower density mark is upwards and higher density mark is downwards.

Assertion : Railway tracks are laid on small sized wooden sleepers. Reason : Large sized wooden sleepers are preferred to decrease pressure on ground.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
Due to large sized wooden sleepers the weight of rail act on the large area. Pressure exerted decreases appreciably. The thrust due to weight of train is spread over large area. This reduces pressure on the ground which prevents the yielding of ground. So correct option is (4).

Assertion : Addition of carbon to iron increases the elastic property. Reason : Carbon and iron belong to same group of elements.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
Pure iron is soft and stretches easily when hot. Impurity increases hardness. So correct option is (3).
