Which of the below statements is true of the following text?

In a study published in April, ①scientists documented chimpanzees eating and sharing boozy fruit for the first time. ②Scientists noted the behavior probably isn’t rare. ③The researchers say their work further supports the “drunken monkey” hypothesis that Dudley proposed two decades ago, which argues that humans inherited an appetite for alcohol from our primate ancestors. At the time, ④scientists were skeptical of this idea. But now, ⑤“what we’re realizing from this work is that our relationship with alcohol goes deep back into evolutionary time, probably about 30 million years,” ⑥Catherine Hobaiter, a primatologist at the University of St. Andrews in Scotland who was not part of the study, tells BBC News’ Elizabeth Dawson and Helen Briggs.
