Question:
When we apply this to young children, it allows us to predict what might be their future caries history - the number of cavities that they'll get by, say, their late 20s or early 30s, says researcher Paul Denny. Called the Caries Assessment and Risk Evaluation (CARE) test, the test measures the relative proportions in saliva of different types of sugar chains called oligosaccharides. The same sugar chains are present on tooth surfaces.
Is this true?

Question:
The attacker wore a bullet-proof vest under his clothes and a backpack containing a knife, an axe and a fake pistol. Two other knives were found near the crime scene. The prosecutor confirmed that the man's face was painted white with blackened eyes as he committed the crime, which led international media to make comparisons to the Joker, the villain from the Batman series. "I have a question," the killer told the first employee he encountered, after which he immediately stabbed her, and started his rampage. One female day care worker attempted to disarm the killer while others locked the doors. The killer stabbed employees trying to carry children to safety.

Joker appears in the Batman series.
