Q: story: A man has been charged with a federal hate crime in connection with what authorities say was a racially motivated "knockout" assault against an elderly black man, the U.S. Justice Department said Thursday.

Conrad Alvin Barrett, 27, of Katy, Texas, has been charged with one count of violating the Matthew Shepard and James Byrd Jr. Hate Crimes Prevention Act.

According to the federal complaint, Barrett attacked the 79-year-old man "because of the man's race and color." He will next appear in court Friday afternoon for a detention hearing.

The suspect made a video of the attack November 24, the complaint said. In the video, he allegedly commented that "the plan is to see if I were to hit a black person, would this be nationally televised?"

He then allegedly "hit the man with such force that the man immediately fell to the ground. Barrett then laughed and said 'knockout,' as he ran to his vehicle and fled."

The victim suffered two jaw fractures and was hospitalized for several days, the complaint said.

Barrett's attorney, George Parnham, told CNN the affidavit does not "pull back the layers of mental health."

His client has bipolar disorder and takes medication, Parnham said in an earlier call.

Parnham said he could not state whether his client carried out the attack, but, "mental health issues definitely played a part in anything that occurred."

Barrett "is very sorry for this person," Parnham said, adding that he and his client haven't had much opportunity to discuss the facts of the case. , question: What is the name of the attacker?

A: Conrad Alvin Barrett

Q: story: Traditionally considered the last part of the Stone Age, the Neolithic followed the terminal Holocene Epipaleolithic period and commenced with the beginning of farming, which produced the "Neolithic Revolution". It ended when metal tools became widespread (in the Copper Age or Bronze Age; or, in some geographical regions, in the Iron Age). The Neolithic is a progression of behavioral and cultural characteristics and changes, including the use of wild and domestic crops and of domesticated animals.

The beginning of the Neolithic culture is considered to be in the Levant (Jericho, modern-day West Bank) about 10,200 8,800 BC. It developed directly from the Epipaleolithic Natufian culture in the region, whose people pioneered the use of wild cereals, which then evolved into true farming. The Natufian period was between 12,000 and 10,200 BC, and the so-called "proto-Neolithic" is now included in the Pre-Pottery Neolithic (PPNA) between 10,200 and 8,800 BC. As the Natufians had become dependent on wild cereals in their diet, and a sedentary way of life had begun among them, the climatic changes associated with the Younger Dryas are thought to have forced people to develop farming., question: When was the Natufian period?

A:
between 12,000 and 10,200 BC
