Question 1: If a figure is described as having bilateral symmetry, how many lines of symmetry does it have?
Question 2: Why is Batman also known as 'The Dark Knight'?
Batman earned the nickname 'The Dark Knight' because unlike many superheroes, he does not shy away from ruthless methods to combat his foes, and because he largely operates under the cover of darkness.

Question 3: Why is crop rotation beneficial?
Crop rotation is the practice of growing different types of crops in the same area across different growing seasons. This agricultural practice helps to maintain soil fertility and structure, as different crops have different nutrient requirements and contribute differently to the soil structure. This reduces the need for synthetic fertilizers and improves crop yields in the long term.
Question 4: How long does it take for a plastic bottle to decompose?
Plastic bottles are one of the most common types of plastic waste. They are made from a type of plastic called polyethylene terephthalate (PET), which takes a very long time to break down in the environment.
Question 5: What is the world's largest island?
Greenland, an autonomous territory within the Kingdom of Denmark, is the world's largest island, covering an area of 2,166,086 square kilometers (836,330 square miles). Despite its name, approximately 79% of Greenland's surface is covered by an ice sheet.
Question 6: If a plant's flowers contain both male and female reproductive parts, it is known as what?
Flowers that contain both male (stamen) and female (pistil) reproductive parts in the same flower are called perfect flowers. Most flowers of angiosperms are perfect. Examples include roses, lilies, and daffodils.

Question 10: Why does the Leaning Tower of Pisa lean?
The Leaning Tower of Pisa leans because it was built on an unstable foundation. The ground was too soft on one side to properly support the structure's weight, causing the tower to tilt during construction in the 12th century. The lean has been partially corrected through stabilization projects over the years.
Bilateral symmetry refers to a figure being divisible into symmetrical halves on only one plane. This means objects with bilateral symmetry have only one line of symmetry.
