Answer: The Generalised Slowing Hypothesis Theory
Explanation:
The Generalised Slowing Hypothesis is built upon wide observations in many studies of age related slowing and suggests that it is the primary contributor to the declines in cognitive functioning seen with aging.
As people age, B lymphocytes and T lymphocytes become less active. These cells secrete antibodies and are thus crucial to the immune system. T cells are made in the thymus which shrinks as aging occurs. Thus reducing the body's ability to fight infections as aging occurs.
Through the normal aging process, DNA is damaged by environmental factors such as pollutants and toxic agents. As a result, there is deletions of genetic material and mutations in DNA replicated in new cells. Reduced functioning in cells and tissues occur when these errors accumulate.
Also as aging occurs, glucose molecules attach themselves to proteins and form cross links. These crosslinks reduce the flexibility of tissues making them become stiff. The circulatory systems becomes less efficient since the tissues of the lungs, heart and arteries lose flexibility.

The red marbles are examples EXTRINSIC PUNISHERS
Explanation:
Extrinsic punishers are used in behavioural management. Extrinsic punishers are reinforcements or methods that are used to make people who would not do what is right to do the right things as because they would get certain reward as consequences for their wrong behavior and not because it is the right thing to do.
Extrinsic punishers help to modify and correct the wrong behaviors in people. Extrinsic punishers also help to reinforce good and proper behavior in people.
Extrinsic punishers can also be called Secondary or generalized punishers.
In these question above the red marbles are extrinsic punishers because when people receive the red marbles they know it signifies that they have done something bad and it has consequences so they try next time to behave better and improve their behavior next time so that they can receive the green marbles instead of the read marbles.
