Read the passage and answer the four questions that follow:-
Until a hundred years ago as humans, we had a simple, uncomplicated biological connect with nature. It was a straightforward equation: we drew roughly 3,000 calories each of energy out of the Earth for our food and life's sustenance. Today that number per capita has grown to 1,00,000 calories. We still need only 3,000 calories each to nourish life itself. All the rest of this energy is what we extract from the Earth for everything else besides keeping ourselves alive.
How to soften this abuse of resources? What is sustainable development? How can it be started in our homes? Beyond the ceremonial planting of green and getting people to run marathons of various lengths in support of the environment, is there more that we can add to the abstract value of "sustainability"? What are the little things we can do in our day-to-day lives, to reduce the demand for things that people make and market? Of course, we know that it helps to avoid a plastic bag when you can use a newspaper bag, or a brown bag, or even a jute bag, which you can use for many more years.
However, there's actually quite a bit more that you and I can do, with very little as cost incurred, and with solutions that are very feasible and within our reach. It is possible to understand our ecological footprint and its disastrous consequences, in terms of the impact on the environment that we make.
A suitable title for the passage could be:-
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Save Energy, Save the Earth!
The passage contrasts the energy we need with the far larger energy we extract from the Earth, and asks what we can do to reduce this demand. Using less energy to protect the Earth is the whole theme, so "Save Energy, Save the Earth!" is the most suitable title.
Why the Other Options are Incorrect?
Option 1: Let's Shift to Jute! — Incorrect. Too narrow: the jute bag is only one small example, not the subject of the passage.
Option 2: How to Consume Fewer Calories — Incorrect. Misread: this sounds like advice on diet; the passage uses calories only to measure the energy we take from the Earth.
Option 4: The Earth Heading for a Disaster. — Incorrect. Wrong focus: the passage mentions disastrous consequences only in passing; its focus is on what we can do, with feasible solutions within our reach.
