Directions: Read the passage and answer the question.

The functional declines of advancing age are depressing. The heart’s ability to pump blood drops about one per cent: blood flow to arms and legs decreases by thirty to forty per cent in old age. The amount of air a person can exhale after a deep breath lessens and the chest wall stiffens with age. However, recent studies have shown that most of these age associated declines can be delayed by exercise. Exercise lowers the resting heart - rate and increases the amount of blood pumped with each beat in older people. When stress is placed on bones through exercise, calcium content rises, with the result that resistance to fracture is improved.

  1. increases the amount of blood pumped by the heart

What is the positive effect of Artificial sweeteners?

Directions: Read the passage given below and answer the question.

Bloating can be caused by a variety of factors like health issues, genetics, or medications; but it can also be caused by the foods we eat. Although we may be eating a healthy diet, some foods like broccoli and milk can cause painful gas and bloating that’s as uncomfortable as it is unsightly. Here is a list of six bloating culprits to watch out for.
Broccoli Although filled with fibre and vitamins, broccoli can also cause gas and bloating. Try eating broccoli very slowly to reduce gas.
Artificial sweeteners They may save on calories, but artificial sweeteners contain sugar alcohols which can cause bloating. Minimise your use of artificial sweeteners or skip them altogether to reduce uncomfortable gas.
Chewing gum While it may help to digest your food and keep your teeth white, chewing gum can bring excess air into your digestive system, which causes gas. Chew gum slowly to reduce gas.
Cabbage Delicious and healthy cabbage is a great vegetable to enjoy all year round. But this leafy veggie can also spur painful bloating. Avoid it or try eating it slowly for relief.
Carbonated drinks Although some popular sodas were created to help digestion, they may cause bloating as well. Limit your consumption of these bubbly treats to keep your digestive system on track.
Milk It may be filled with vitamins and nutrients, but milk is a major offender of bloating and gas. Try opting for lactose-free milk or almond milk for relief without sacrificing the milky taste.

C Correct answer
Explanation

Antioxidants protect the body's cells against oxidants or free radicals. These can damage the cell's surface, alter its DNA or completely kill the cell. Oxidants or free radicals cause oxidative stress if the body does not have time to take care of them. It can lead to diseases. A diet naturally rich in antioxidants helps to protect the body. Fruits and vegetables are rich in antioxidants. So, fruits and vegetables are classed as protective food. Fruits and vegetables are good sources of vitamins and minerals. The recommended daily intake of green vegetables and fruits are 40 g and 85 g respectively.
