Green Skills

Correct answer: C. Helps with cleanliness and conservation activities

An environmental volunteer gives time and effort to activities that protect or improve the natural and community environment. Typical responsibilities include joining cleanliness drives, planting and caring for trees, separating waste, supporting recycling or composting, conserving water, monitoring local surroundings, and spreading accurate environmental awareness. The work may be unpaid, but it is valuable because collective participation can make public spaces healthier and safer. Option C is correct because cleanliness and conservation are central volunteer activities. Spreading waste, cutting trees without a legitimate conservation purpose, and polluting water damage the environment and contradict the role. Volunteering also requires cooperation, responsibility, and safe conduct.

Correct answer: D. Goals to save water and electricity and reduce waste

A personal green action plan is a written set of practical, measurable steps through which an individual reduces environmental harm. It may include taking shorter showers, turning off lights and fans when not needed, carrying reusable items, segregating waste, repairing or reusing products, using public transport, and planting or caring for trees. A good plan can state a target, a time period, and a way to monitor progress. Option D is correct because saving water and electricity and reducing waste are conservation goals. The other options deliberately promote waste, littering, or careless water use, so they oppose green action.

Correct answer: A. Progress in improvement can be measured

Tracking green habits means recording or reviewing actions such as electricity use, water consumption, waste segregation, use of public transport, or avoidance of disposable items. The record creates a baseline and allows a person to compare performance over time. For example, checking monthly electricity units can show whether switching off unused appliances is making a difference. It can also reveal weak areas and encourage realistic new targets. Therefore, option A is correct because tracking measures progress and supports improvement. It does not hide environmental effects, guarantee that wastage will increase, or remove the need to change habits; instead, it makes responsible change easier to observe and sustain.

Correct answer: B. Use according to need and responsibility

Ethical use of resources means using water, energy, land, materials, and other shared resources carefully, fairly, and only for a justified need. It considers how present choices affect other people, vulnerable communities, animals, and future generations. In practice, this involves avoiding unnecessary consumption, preventing pollution, repairing and reusing goods, sharing fairly, and disposing of waste safely. Option B is correct because it combines need with responsibility and fairness. Wasting resources, taking an unfair share, or deliberately harming nature ignores the rights and well-being of others. Ethical use therefore connects environmental care with social responsibility, not merely personal convenience.

Correct answer: C. Sustainable development

Sustainable development means meeting the needs of people today while protecting the ability of future generations to meet their own needs. It seeks a balance among economic progress, social well-being, and environmental protection. Saving water, using energy efficiently, protecting forests, reducing waste, and choosing renewable resources are examples of actions that support this balance. Option C is correct because conserving resources for the future is a central principle of sustainable development. Excessive wastage, unplanned pollution, and littering reduce the quality and availability of resources, so they work against sustainability rather than supporting it.

Correct answer: D. Green technology

A solar-powered street light uses photovoltaic panels to convert sunlight into electrical energy, usually storing some energy in a battery for use after sunset. Because sunlight is a renewable energy source, the system can reduce dependence on conventional fossil-fuel-based electricity and may lower operating emissions. It also provides useful public lighting when designed, installed, and maintained properly. Therefore, option D is correct because a device that applies renewable energy to meet a practical need is an example of green technology. It is not inherently fuel wastage, noise pollution, or water pollution, although all equipment should still be managed responsibly at the end of its useful life.

Correct answer: A. Responsibility towards nature

The governing concept is environmental responsibility, an important part of green skills. When students plant a classroom plant and care for it, they practise watering it carefully, protecting the soil, keeping the surroundings clean, and understanding that living things need attention. These actions build respect and responsibility towards nature. Therefore, option A is correct. Littering, wasting water, and increasing pollution are not responsible behaviours; they damage the environment rather than protect it. A classroom plant also makes sustainability a regular, practical habit instead of only a textbook idea.
