85. Assertion A : Poverty is a basic cause of undernutrition in children

Reason R : Poverty contributes to undernutrition by adversely influencing food and nutrition security, housing and living environment with increased risk of infections

Correct Answer: (a) Both A and R are true and R is the correct explanation of A
Solution:

Poverty is basic cause of undernutrition in children as it result in low food availability, overcrowded and unsanitary living conditions and improper care of child.

86. Assertion A : When disperse dyes are applied to polyesters at low temperatures, carriers are required to bring about penetration of the dye molecules into the fiber.

Reason R : High pressure and high temperature eliminates the need for carriers.

Correct Answer: (a) Both A and R are true and R is the correct explanation of A
Solution:

When disperse dyes are applied to polyesters at low temperatures, carriers are required to bring about penetration of the dye molecules into the fiber. But high pressure and high temperature eliminates the need for carriers

87. Assertion A : Longer outside walls should run in east-west direction and shorter ones in north-south direction.

Reason R : This causes minimum wall area to expose to the direct sun rays and thus cause less absorption and radiation of heat.

Correct Answer: (a) Both A and R are true and R is the correct explanation of A
Solution:

As the sun rises in the east culminates in the south and sets in the west so, the longer outside wall should run in east-west direction which causes minimum wall area to expose to the direct sunrays and thus cause less absorption and radiation of heat.

88. Assertion A : A doctor develops a vaccine with an intent of preventing future spread of infections, but it harms people. This cannot be considered as an aggressive act.

Reason R : An important aspect of aggressive behaviour is the intention underlying the actors behaviour. Not all behaviours resulting in harm are considered aggression.
