The history of the electric bicycle, or e-bike, dates back to the 19th century when the first electric bicycle prototype was developed. However, it wasn't until the 1990s that the e-bike started gaining popularity, and today it is a common mode of transportation in many parts of the world.

The first electric bicycle prototype was developed in 1895 by Ogden Bolton Jr., an American inventor. His electric bicycle had a motor attached to the rear wheel and was powered by a battery. However, the invention did not gain much traction at the time due to the limitations of the battery technology available.

It wasn't until the 1990s that e-bikes started becoming popular. In 1992, Yamaha introduced its first e-bike, which had a pedal-assist system that used a sensor to detect the rider's pedalling and activate the motor. This made the e-bike more efficient, as the motor only provided power when the rider needed it.

In 1997, the first commercially successful e-bike was launched by Lee Iacocca, the former CEO of Chrysler. His company, EV Global Motors, introduced the e-bike as a stylish and eco-friendly alternative to traditional bikes. The e-bike had a top speed of 15 mph and a range of 20 miles per charge.

In the following years, e-bikes became increasingly popular in Europe, where they were used for commuting and transportation. In 2005, the Chinese company Bafang introduced a new type of e-bike motor that was more efficient and reliable, which led to a surge in the popularity of e-bikes in China.

Today, e-bikes are a common mode of transportation in many parts of the world. They are used for commuting, exercise, and recreation, and come in a variety of styles and designs. The advancements in battery technology and motor efficiency have made e-bikes more practical and accessible, and they are seen as a sustainable and eco-friendly alternative to traditional cars and motorcycles.

Articles and Determiners in English

Articles and determiners are words that provide information about nouns. In English, there are three articles: "a," "an," and "the." These articles help to indicate whether a noun is definite or indefinite.

Indefinite Articles: "a" and "an"

Indefinite articles are used when talking about non-specific, singular countable nouns. There are two indefinite articles in English:

• A: Use "a" before a consonant sound (e.g., a book, a cat, a university).
• An: Use "an" before a vowel sound (e.g., an apple, an egg, an hour).

Definite Article: "the"

The definite article "the" is used when talking about specific, known nouns. It can be used with both singular and plural nouns, as well as countable and uncountable nouns. For example: the book, the apples, the information.

Zero Article

Sometimes, English sentences don't require an article. This is known as the "zero article." The zero article is used with:

• Plural countable nouns when talking about them in general (e.g., Dogs are loyal animals).
• Uncountable nouns when talking about them in general (e.g., Information is valuable).
• Proper nouns (e.g., London is a beautiful city).

In this exercise, you'll practice identifying and using the correct articles and determiners in English. Fill in the blanks with the appropriate article: "a," "an," or "the."
