示例

- "In fact, a well-rested staff is exponentially more productive than a tired one."

According to the report mentioned in this article:
According to the report mentioned in this article:
This is not correct. The report says that weight gain is "steady from coast to coast, from California to New York", and the report was carried out in "all 50 states". In this context, "steady" means there are no significant variations. "Steady" growth is "certain" or "continuous". For example: "There has been a steady increase in the number of cars on the road in Britain".
This is not correct. The report says that "naive idealists and conservatives" believe that obesity is becoming less of a problem, but that this is not true.
This is not correct. At first, scientists thought that the result was an anomaly or a mistake. However, more tests confirmed that the data was correct. To "gather (data)" is to accumulate or find information.
This is correct. If something increases at an "exponential rate", it grows extremely quickly. The term "weight gain" describes the increase in size or heaviness of a person: they are getting fatter. Example: "Rapid weight gain is a good thing during pregnancy, but women should lose some weight when the baby is born".
