Question: When was the Bronze age? Passage:It was first studied by Lorraine Copeland and Peter Wescombe in 19651966. A wide variety of materials were recovered from the site and its immediate area that are now held in the Saint Joseph University in Beirut. Stone tools from the surface included numerous short, wide, sickle blades with fine denticulation or nibbling along with tanged arrowheads, scrapers, chisels, axes, burins, obsidian and a small green stone axe. Pottery resembled middle periods at Byblos and coloured similar to at Ard Tlaili with red or black washes. Both fine and coarse shards were found of jars with a variety of collared and flared necks and flat bases along with bow rims such as those found at Jericho. Vessels were decorated with stabbed and incised designs, finger pressed around the rim and smoothed by hand or with straw. A painted lattice pattern was detected on at least one piece. Comparisons were made with middle and late Neolithic periods at Byblos showing inhabitation from several phases. The site was also used in Bronze Age and Classical times and material from these phases has been found over a wide area around the site.

Question: Is Marv's son younger than his successor? Passage:Marv did his first Knicks game on January 27, 1963 on WCBS Radio. He filled in for his mentor, Marty Glickman, who was away in Europe. The game was against the Celtics at the Boston Garden. For 37 years beginning in 1967, Albert was the voice of the New York Knicks on radio and television (getting his start by being a ball boy for the Knicks before getting his first break on New York radio by sportscaster Marty Glickman) before being let go by James L. Dolan, the chairman of the MSG Network and Cablevision, after Albert criticized the Knicks' poor play on-air in 2004. It was said that Marv's high salary was also a factor. His son Kenny Albert has been a part-time play-by-play announcer for the Knicks since 2009, whenever the older Albert's successor Mike Breen (whom he later followed on the NBA on NBC broadcasts and now works on ESPN and ABC aside from his role at MSG) is unavailable.
