2.
The process by which green plants use light energy to make food is called____
Correct Answer
A. pHotosynthesis
Explanation
Photosynthesis is the correct answer because it is the process by which green plants use light energy to convert carbon dioxide and water into glucose and oxygen. During this process, plants capture sunlight through their chlorophyll pigments and use it to produce food for their growth and survival. The glucose produced through photosynthesis is used as a source of energy for various cellular activities in plants.
3.
Solar energy is derived from _____
Correct Answer
C. Sun
Explanation
Solar energy is derived from the sun. The sun is a massive ball of hot gases that emits large amounts of energy in the form of heat and light. Solar energy is harnessed by using technologies like solar panels to convert sunlight into usable electricity. The sun's rays contain photons, which are absorbed by the solar panels and converted into electricity through a process called the photovoltaic effect. Therefore, the sun is the primary source of solar energy.
4.
The first computer was invented by_____
Correct Answer
B. Charlse Babbage
Explanation
Charles Babbage is credited with inventing the first computer. He was an English mathematician and inventor who designed the Difference Engine and the Analytical Engine in the 19th century. The Analytical Engine is considered to be the first general-purpose computer, although it was never built during Babbage's lifetime. Babbage's contributions laid the foundation for modern computing and his work is highly influential in the field of computer science.
5.
The boiling point of water is at ____
Correct Answer
B. 100 degree celcius
Explanation
Water boils at 100 degrees Celsius because this is the temperature at which the vapor pressure of water equals the atmospheric pressure. At this temperature, water molecules have enough energy to overcome the attractive forces between them and transition from the liquid phase to the gaseous phase. Any temperature below 100 degrees Celsius will not provide enough energy for water molecules to escape into the gas phase, while temperatures above 100 degrees Celsius will result in the water molecules reaching higher energy levels and potentially ionizing or decomposing.
6.
What is the shape of the earth?
Correct Answer
C. SpHere
Explanation
The correct answer is sphere because the shape of the Earth is approximately spherical. A sphere is a three-dimensional shape in which all points on the surface are equidistant from the center. The Earth's shape is not perfectly spherical, as it is slightly flattened at the poles and bulging at the equator due to its rotation. However, it is still best described as a sphere, making this the most accurate answer.
7.
All these insects undergo complete metamorphosis except_____
Correct Answer
D. Bee
Explanation
The bee is the correct answer because it undergoes incomplete metamorphosis, not complete metamorphosis like the other insects listed. In complete metamorphosis, the insect goes through four distinct stages: egg, larva, pupa, and adult. However, bees go through three stages: egg, larva, and adult. They do not have a pupal stage where they undergo significant physical changes.
8.
The freezing point of water is at_____
Correct Answer
A. 0
Explanation
The freezing point of water is at 0 degrees Celsius. At this temperature, water changes from a liquid state to a solid state, forming ice. This is a well-known fact in science and is widely accepted.
9.
The sound of an elephant is ____
Correct Answer
A. Trumpeting
Explanation
The sound of an elephant is often described as "trumpeting". This is because elephants produce loud, trumpet-like calls through their long trunks. These calls can serve various purposes, such as communication, expressing emotions, or warning other elephants of potential danger. The term "trumpeting" accurately captures the unique and distinct sound that elephants make.
10.
A house is for man as a coop is for ____
Correct Answer
D. Hen
Explanation
A house is a shelter or dwelling place for a man. Similarly, a coop is a shelter or enclosure specifically designed for a hen. Both a house and a coop provide protection and a safe space for their respective occupants. Therefore, the correct answer is hen.
11.
______ lives in a pen as _____ lives in the jungle.
Correct Answer
B. Goat, elepHant
Explanation
The given sentence is comparing where different animals live. It states that "______ lives in a pen as _____ lives in the jungle." The correct answer is "Goat, elephant" because goats are commonly kept in pens or enclosures, while elephants are typically found in the jungle or natural habitats. Therefore, the comparison between the two animals' living environments is accurate.
12.
The dog _____ while the bear_____
Correct Answer
C. Barks, growls
Explanation
The correct answer is "barks, growls" because it is more common for a dog to bark and a bear to growl. Barking is a typical vocalization for dogs, while growling is more characteristic of bears.
13.
The home of a rabbit is called a___
Correct Answer
C. Burrow
Explanation
A rabbit's home is called a burrow because rabbits dig tunnels in the ground to create a safe and secure place for themselves and their young. These burrows provide protection from predators and extreme weather conditions. The tunnels are usually interconnected and have multiple entrances and exits, allowing the rabbit to escape quickly if necessary. Inside the burrow, the rabbit creates separate chambers for sleeping, nesting, and storing food. The burrow also helps regulate the rabbit's body temperature, as it stays cool in the summer and warm in the winter.
14.
A spider lives in a ____
Correct Answer
B. Web
Explanation
A spider lives in a web, which is a structure made of silk that the spider spins to catch its prey. The web acts as a home and a trap for the spider, allowing it to capture insects and other small creatures for food. Spiders are known for their ability to create intricate and strong webs, which serve as their primary means of survival and reproduction.
15.

A ____ is found in a first aid box.
Correct Answer
B. Scissors
Explanation
Scissors are commonly found in a first aid box because they are a versatile tool that can be used for cutting various materials such as bandages, gauze, and clothing.
