Do you want your kids to grow up to be successful? If yes, make them do chores. When they balk (and trust me, they probably will), you can tell them that scientific research supports you.

In a Harvard Grant Study, researchers identified two things that people need in order to be happy and successful. The first is love. The second is work ethic.

(1) Developing Work ethics in young people is not easy. Based on the experience of 714 high-achievers who were part of the study (including people like future President Kennedy), there’s a consensus.

The study found that professional success in life (2) comes from chores done as a kid. “The earlier you start, the better,” according to Lythcott-Haims, editor of ‘How to Raise an Adult.’ “A roll-up-your-sleeves-and-pitch-in-mindset, a mindset that says, (3) there’s some unpleasant work, someone’s got to do it, might as well be me - that’s what gets you ahead in the workplace.”

(4) Here’s the drawback. It’s that having your kids do chores doesn’t necessarily wind up being less work for you as a parent. But sometimes, even if you could do a job perfectly, you have to let someone else do it, even if just passably, (5) if you want, the other person to learn from experience. It’s the same principle whether we’re talking about training soldiers for the army, or letting kids empty the dishwasher.

Questions 12-15: Read the following paragraph and answer the questions.

Scholars once proclaimed that the agricultural revolution was a great leap forward for humanity. They told a tale of progress fueled by human brain power. Evolution gradually produced ever more intelligent people. Eventually, people were so smart that they were able to decipher nature’s secrets, enabling them to tame sheep and cultivate wheat. As soon as this happened, they cheerfully abandoned the grueling, dangerous, and often spartan life of hunter-gatherers, settling down to enjoy the pleasant, satiated life of farmers.

That tale is a fantasy. There is no evidence that people became more intelligent with time. Foragers knew the secrets of nature long before the Agricultural Revolution, since their survival depended on an intimate knowledge of the animals they hunted and the plants they gathered. Rather than heralding a new era of easy living, the Agricultural Revolution left farmers with lives generally more difficult and less satisfying than those of foragers. Hunter-gatherers spent their time in more stimulating and varied ways, and were less in danger of starvation and disease. The Agricultural Revolution certainly enlarged the sum total of food at the disposal of humankind, but the extra food did not translate into a better diet or more leisure. Rather, it translated into population explosions and pampered elites. The average farmer worked harder than the average forager, and got a worse diet in return. The Agricultural Revolution was history’s biggest fraud. Who were responsible? Neither kings, nor priests, nor merchants. The culprits were a handful of plant species, including wheat, rice, and potatoes. These plants domesticated Homo Sapiens, rather than vice versa.
