Read the passage below to determine the central idea / main idea:

Urban Farms: 

Many people wrongly think that cities don’t have farms and that fruits and vegetables are only grown in the country. Believe it or not, there are more and more urban farms popping up in cities all over the world.

Alexandra Sullivan, a food systems researcher in New York City, studies urban agriculture. Urban agriculture is another name for farming and gardening in a city environment. Ms. Sullivan studies everything from tiny gardens in empty lots between buildings to bigger fields that have been planted and cultivated. According to Ms. Sullivan, “Urban agriculture has existed since cities have, across the world.” 

The number of humans living in urban areas, or cities, is increasing. The amount of people who want to garden in urban areas is also rising. Ms. Sullivan says, “In small gardens, on rooftops and indoors, city residents grow fruits, vegetables, grains, and herbs, and raise animals to produce dairy, eggs, honey, and meat. City residents use these foods as supplements [additions] to food produced by rural agriculture.” Even though some people who live in urban areas grow crops, urban residents still need to rely on food grown in rural areas. This is because a city doesn’t have enough space to grow enough food for everyone living in it.

In New York City, urban farmers have come up with many different ways to grow their own produce, even though there isn’t a lot of room. For example, Brooklyn Grange is a farming operation that has two rooftop vegetable farms in New York City. All together, the farms are made up of 2.5 acres of rooftop space. This makes Brooklyn Grange, one of the largest rooftop farming operations in the world. 

Brooklyn Grange grows tomatoes, lettuce, peppers, kale, chard, herbs, carrots, radishes, and beans. The farming company sells its vegetables to local residents and restaurants. And because the farms are on rooftops, they are specially adapted to their urban location. They use available space that is not needed for anything else. As more urban farmers find ways to grow food in cities, urban residents will be better able to get fresher ingredients for their meals.

READ THE PASSAGE:

The first potato chips were invented in 1853 in a New York hotel kitchen by Chef George Crum. When he invented them, he hoped that they would taste bad. You see, he was irritated with a cranky guest who had complained that Crum’s potatoes were too soggy, thick, and bland. The guest had requested that Crum make him a new batch. Chef Crum wanted to “teach the guest a lesson” about insulting the chef, so he made a batch that was paper-thin, overcooked, and oversalted. To his surprise, the diner loved the second batch! Word spread quickly, and potato chips became a very popular snack.

What is the main idea of this passage?

• You should never insult a chef.

• Potato chips are oversalted and paper thin.

• Potato chips were invented in a New York City hotel kitchen.

• Chef George Crum invented the potato chips when he was trying to insult a picky diner.
