Answer :
Here are the answers to the questions along with detailed explanations:
A/An ____ is a machine that keeps a room's temperature cool.
- c. air conditioner
An air conditioner is a device designed to cool the air in a specified area. It provides comfort by managing indoor temperature and humidity. While a fin and fridge are related to cooling in different contexts (a fin in heat exchangers and a fridge for food), an oven is used for heating, not cooling.
I want to have an air conditioner that uses less electricity. "Less" is an antonym for "____".
- b. more
"Less" and "more" are antonyms. "Less" indicates a smaller amount of something, while "more" indicates a larger amount. In terms of electricity consumption, using "less" electricity means consuming a smaller amount, while "more" would mean consuming a greater amount.
A ____ environment is a place where there is very little or no pollution.
- c. greener
The term 'greener' refers to an environment with minimal pollution, often synonymous with being eco-friendly or environmentally sustainable. It implies an emphasis on clean air, recycling, reduction of waste, and the use of resources that don't harm the planet. Greener environments are important for healthy living and sustainability.
