Which one of the following is a desirable change?

Answer: We understand that change is a natural process that occurs at all times and on a daily basis in our lives. There are two types of changes: desired changes and undesired changes. In simple language, desirable changes are those that we want to happen, whereas undesirable changes are those we don’t want to happen.

Complete Answer:

Changes can be good (desirable) or bad (undesirable). A desirable change is one that is helpful and needed in our daily lives. An undesirable change is harmful or causes damage.

Let us look at each option:

(A) Burning of the house: This is dangerous and harmful. It causes loss of property and life. So, it is an undesirable change.

(B) Floods: Floods damage houses, crops, and roads. They are natural disasters and are also undesirable.

(C) Landslides: These destroy homes and block roads. They can be very dangerous. So, they are undesirable too.

(D) Burning of cooking gas: This is useful. We burn cooking gas (LPG) every day to make food. It is a planned and helpful change, so it is a desirable change.

So, the correct answer is (D) Burning of cooking gas, because it helps us in cooking and is not harmful when used properly.

Conclusion: Because cooking gas is lighter than air and can disperse easily, a leak will be difficult to detect because it is colourless, odorless, and tasteless, and because it is highly combustible, it can cause damage, but it is still one of the most viable alternatives to other fossil fuels.
