Reаding Sectiоn 2: Reаd the text belоw аnd answer the questiоns following it. BicyclesToday, bicycles are elegantly simple machines that are common around the world. Many people ride bicycles for recreation, whereas others use them as a means of transportation. The first bicycle, called a draisienne, was invented in Germany in 1818 by Baron Karl de Drais de Sauerbrun. Because it was made of wood, the draisienne wasn’t very durable, nor did it have pedals. Riders moved it by pushing their feet against the ground.In 1839, Kirkpatrick Macmillan, a Scottish blacksmith, invented a much better bicycle. Macmillan’s machine had tires with iron rims to keep them from getting worn down. He also used foot-operated cranks, similar to pedals, so his bicycle could be ridden at a quick pace. It didn’t look much like the modern bicycle, though, because its back wheel was substantially larger than its front wheel. Although Macmillan’s bicycles could be ridden easily, they were never produced in large numbers.In 1861, Frenchman Pierre Michaux and his brother Ernest invented a bicycle with an improved crank mechanism. They called their bicycle a vélocipède, but most people called it a “bone shaker” because of the jarring effect of the wood and iron frame. Despite the unflattering nickname, the vélocipède was a hit. After a few years, the Michaux family was making hundreds of the machines annually, mostly for fun-seeking young people.Ten years later, James Starley, an English inventor, made several innovations that revolutionized bicycle design. He made the front wheel many times larger than the back wheel, put a gear on the pedals to make the bicycle more efficient, and lightened the wheels by using wire spokes. Although this bicycle was much lighter and less tiring to ride, it was still clumsy, extremely top-heavy, and ridden mostly for entertainment.It wasn’t until 1874 that the first truly modern bicycle appeared on the scene. Invented by another Englishman, H.J. Lawson, the safety bicycle would look familiar to today’s cyclists. The safety bicycle had equal-sized wheels, which made it much less prone to toppling over. Lawson also attached a chain to the pedals to drive the rear wheel. By 1893, the safety bicycle had been further improved with air-filled rubber tires, a diamond- shaped frame, and easy braking. With the improvements provided by Lawson, bicycles became extremely popular and useful for transportation. Today, they are built, used, and enjoyed all over the world. The first person to use a gear system on bicycles was:

Reаding Sectiоn 1: Reаd the pаssage. Then, chооse the letter of the best answer for each question.The Right Job for your PersonalityChoosing a career is an important life decision, yet many people settle on one based on the opinions of friends and family. It’s very difficult to find something you really enjoy doing, but scientists have devised tests to help people come closer to finding their dream job. One of the most widely used tests is the Holland Code. Psychologist John Holland worked for more than 50 years to develop his theories about personality and career choice. He created a set of six personality types to help people understand what careers might be best for them. Dr. Holland believed that people work best in environments that match their personalities, and the key to finding a satisfying career is to match your fundamental interests with an occupation.Take a look at the six personality types below and see which jobs might be right for you. Most people are a combination of two or three types. RealisticRealistic people like to work with things they can see or touch.
