Q: Question: How high is the mountain in the Port Hills that the Christchurch Gondola traverses? Passage 1:After spending many years training in the United Kingdom the 197th Brigade, together with the rest of the 59th Division, landed in France on 29 June 1944, D-Day + 23. The division, under command of XII Corps, became part of the British Second Army, which was engaged in the Battle for Caen. With the arrival of the 59th Division General Bernard Montgomery, commanding the Anglo-Canadian 21st Army Group, decided to renew the offensive to capture the city of Caen, which was originally a D-Day objective for the British 3rd Infantry Division which ultimately failed, due mainly to heavier resistance than expected. Operation Charnwood. The brigade's first action was Operation Charnwood with 2/6th South Staffords (of 177th Brigade), along with C Company of the 7th Battalion, Royal Northumberland Fusiliers (the divisional MG Battalion), together with numerous units of the Royal Artillery under command (and 510 Field Company, RE), and supported by the Churchill tanks of the 1st East Riding Yeomanry (of 27th Armoured Brigade).

 Passage 2:The knifetooth sawfish (Anoxypristis cuspidata), also known as the pointed sawfish or narrow sawfish, is a species of sawfish in the family Pristidae, part of the Batoidea, a superorder of cartilaginous fish that includes the rays and skates. Sawfish display a circumglobal distribution in warm marine and freshwater habitats. Their extant biodiversity is limited to five species belonging to two genera (Pristis and Anoxypristis). The sawfishes are characterised by the long, narrow, flattened rostrum or extension on their snout. This is lined with sharp transverse teeth, arranged in a way that resembles the teeth of a saw. It is found in the shallow coastal waters and estuaries of the Indo-West Pacific, ranging from the Red Sea and the Persian Gulf to southern Japan, Papua New Guinea and northern Australia. It is the only living member of the genus Anoxypristis, but was previously included in the genus Pristis. Compared to that genus, Anoxypristis has a narrower rostral saw with numerous teeth on the distal part and no teeth on the basal one-quarter (toothless section about one-sixth in juveniles). This endangered species reaches a length of up to .
