Revision 1

Evidence B: Researchers led studies inwhich participants were woken up from sleep and asked to solve creativepuzzles. People who had dreamed before the tests were more successful atfinding solutions than those who had not dreamed.

EvidenceA: A long-term sleep study linked the content of its subjects'dreams to their emotional states. For example, people who dreamed about theirteeth falling out were often anxious about a major life event.

Evidence A does not directly support the claim. It does not show that dreaming can help people be more creative.

EvidenceA does not come from a credible source. It relies on the opinion of one non-expert and is not based on research.

Evidence A: The head of a non-profit twin advocacy group notes the importance of dressing twins differently. He explains that distinct outfits are one of many factors that help twins create their own identities.

EvidenceB: A babysitter who blogs about his experiences caring for children shared that he prefers when parents dress their twins differently."Otherwise," he said, "I have trouble telling them apart!"

Evidence B does not directly support the claim. It does not give a reason why twins should dress in different outfits.

Evidence B does not come from a credible source. It is just one non-expert opinion and is not supported by research.

Evidence B: An avid birdwatcher describes the amazing cleverness of a crow in his neighborhood. He writes on his blog that the crow is unlike any other species he's observed, noting that it recognizes his face, his walk, and his car.

Evidence A: Crows, along with humans, are on the very short list of species that can craft and use tools. Biologists who study crows say that the birds' tool-making ability results from their sophisticated thought processes.

Evidence B does not directly support the claim. It does not show the intelligence of crows.

Evidence B is anecdotal. It might not represent the intelligence of crows in general.

Evidence B: A small graphic design company in Oregon rented goats to remove weeds on its grounds. The company's owner noted that the goats"devoured" the English ivy that was harming native plants.

Evidence A: It has been widely demonstrated that goats are enthusiastic eaters who can thoroughly remove stubborn invasive plant species. City and state governments across the U.S. have reported success with using goats for weed control.

Evidence B does not directly support the claim. It does not show that goats are effective at removing weeds.

Evidence B is anecdotal. It rpresents the experience of only one small company.

A prominent financial blogger writes, "My father dropped out of college in his senior year, and he always regretted it. I was determined to not make the same mistake."

The lifetime earnings of a college graduate are about half a million dollars more than those of someone with only a high school diploma.

College graduates are more likely than those who don't have college degrees to report being in excellent health.

"I've hired two people recently who received their college degrees through online programs, and the quality of their performance is as good as, if not better than, that of their peers," reported business owner Peter Pruitt.

Online college programs often provide career preparation services that are equivalent to those provided by traditional college programs, including interview preparation, job fairs, and even internship placement.

Many students choose to gain some credits through an online college program and then successfully transfer to a brick-and-mortar institution to complete a degree.

According to U.S. News &World Report, infections can occur even when tattoo parlors sterilize their needles because bacteria can contaminate the tattoo ink.

One member of an online tattoo forum reported, "I acquired a serious infection after getting my tattoo and needed to take antibiotics."

One survey found that one in six people ultimately come to regret their tattoos.
