Q: Passage: As part of the RAAF's reorganisation following the outbreak of World War II in September 1939, No. 2 Group was formed in Sydney on 20 November; Charlesworth was appointed its Senior Air Staff Officer (SASO). He continued to serve in this position when the group was re-formed as Central Area in March 1940. Posted to Western Australia to take command of RAAF Station Pearce in August, he was promoted to temporary group captain on 1 September 1940. He became Senior Administration Officer at the newly established Western Area, Perth, in January the following year. In September 1942, Charlesworth took over No. 2 Bombing and Gunnery School in Sale, Victoria. He handed over to Group Captain Charles "Moth" Eaton in August 1943, before briefly taking charge of RAAF Headquarters Forward Echelon in Brisbane. Charlesworth was appointed Air Officer Commanding (AOC) Eastern Area, headquartered at Bradfield Park, Sydney, in December 1943. Eastern Area was responsible for maritime patrol and anti-submarine warfare off the coast of New South Wales and southern Queensland. Japanese submarine activity had decreased in the months prior to Charlesworth taking command, and he was concerned that Allied ships were becoming complacent. He observed "a general slackening off in procedure; ships are seldom where they should be, and a minority of merchant ships identify themselves to aircraft". The RAAF's patrols had also settled into a predictable pattern that would have been easy for an observant submarine captain to avoid.

Q: Passage: Although nominally under Seleucid control, Pergamon under Philetaerus enjoyed considerable autonomy. However, upon his succession, Eumenes, perhaps with the encouragement of Ptolemy II, who was at war with the Seleucids, revolted, defeating the Seleucid king Antiochus I near the Lydian capital of Sardis in 261 BC. He was thus able to free Pergamon, and greatly increase the territories under his control. In his new possessions, he established garrison posts in the north at the foot of Mount Ida called Philetaireia after his adoptive father, and in the east, northeast of Thyatira near the sources of the river Lycus, called Attaleia after his grandfather, and he extended his control south of the river Caïcus to the Gulf of Cyme as well. Demonstrating his independence, he began to strike coins with the portrait of Philetaerus, while his predecessor had still depicted Seleucus I Nicator.
 Link Information: Mount Ida is lightly populated upland massif of about 700 km² located to the north of Edremit. A number of small villages in the region are connected by paths. Drainage is mainly to the south, into the , also known as Edremit Bay, where the coast is rugged and is known as "the Olive Riviera.". However, the Karamenderes River (the ancient Scamander) flows from the other side of Mount Ida to the west. Its valley under Kaz Dağları has been called "the Vale of Troy" by English speakers.
Currently a modest 2.4 km² of Mount Ida are protected by Kaz Dağı National Park, created in 1993.

The summit is windswept and bare with a relatively low tree line due to exposure, but the slopes of this mountain, at the edge of mild Mediterranean and colder central Anatolian climate zones, hold a wealth of endemic flora, marooned here after the Ice Age. The climate at lower altitudes has become increasingly hot and dry in the deforested landscape. The dry period lasts from May to October. Rainfall averages between 631 and 733 mm per year. Question: How much annual rainfall does the location where Eumenes established garrisons posts in the north get?

A: Answer: between 631 and 733 mm per year.

Q: Passage: PA 42 begins at an intersection with PA 61 in the near ghost town of Centralia in Columbia County, which has been largely abandoned because of a mine fire. From PA 61, the route heads north on two-lane undivided Locust Avenue. The road passes through abandoned areas of the town which have been overgrown with trees. The route turns east and crosses into Conyngham Township, becoming South Main Street and heading into forested areas. PA 42 becomes a four-lane road and heads to the northwest, passing through the residential community of Aristes, where it narrows back to two lanes. The road curves to the northeast and becomes Numidia Drive, heading into the Weiser State Forest and turning to the northwest as it crosses Big Mountain. The route turns west and northwest through more dense forests, passing to the east of Shamokin Reservoir. Continuing to the west-northwest, PA 42 enters Locust Township as it crosses Little Mountain, leaving the state forest and turning to the north. The road heads into open agricultural areas with some woods and residences. The route briefly turns northwest before heading north again and passing through the community of Numidia. PA 42 curves to the northwest as it heads through more rural areas, crossing the Roaring Creek and continuing into Catawissa Township. The road runs through a mix of farmland and woodland with some homes, gaining a second northbound lane. The route becomes a four-lane road in a wooded area before turning into a three-lane road with one northbound lane and two southbound lanes. PA 42 comes to an intersection with PA 487, at which point that route joins PA 42 for a concurrency, with the two routes heading north through more woodland as a two-lane road. The road crosses the Catawissa Creek into Catawissa and becomes Mill Street, heading northwest into residential areas. PA 42 splits from PA 487 by heading west-northwest on Main Street, heading through the commercial downtown of Catawissa. The road crosses Norfolk Southern's Sunbury Line before heading across the Susquehanna River, at which point the road becomes Rupert Drive and heads into Montour Township. Here, the route turns north and crosses the North Shore Railroad. PA 42 runs through wooded areas immediately to the west of the railroad tracks with the Susquehanna River a short distance to the east. The road turns north-northwest away from the railroad tracks and heads through the residential community of Rupert. The route passes through more woodland with some homes before reaching an interchange with US 11. 
 Link Information: Weiser State Forest encompassed 17961 acre Question: How many acres is the state forest that PA 42 crosses?

A:
Answer: 17961
