Instructions: In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
Input: Passage: Weymouth is built on weak sand and clay rock which in most places along the Dorset coast, except for narrow bands at Lulworth Cove, Swanage and Durdle Door, has been eroded and transported away. This weak rock has been protected at Weymouth by Chesil Beach and the strong limestone Isle of Portland that lies offshore, 3 kilometres (2 mi) south of Wyke Regis. The island affects the tides of the area, producing a double low tide in Weymouth Bay and Portland Harbour. The maximum tidal range is small, at around 2 metres (7 ft).There are two lakes in the borough, both RSPB Nature Reserves—Radipole Lake in the town centre, and Lodmoor between the town centre and Preston. Radipole Lake, the largest nature reserve, and mouth of the River Wey before it flows into Weymouth Harbour, is an important habitat for fish and migratory birds, and over 200 species of plants. Radipole is an important tourist attraction; it and Weymouth Beach are situated very close to the main town centre. There are 11 Sites of Special Scientific Interest in the borough, which cover an area of 800.87 hectares (1,979 acres), and there are 37 other Nature Conservation Designations.Situated approximately halfway along the Jurassic Coast, Weymouth is a gateway town to the UNESCO World Heritage Site, which includes 155 kilometres (96 mi) of the Dorset and east Devon coast that is important for its geology and landforms. The South West Coast Path has two routes around Weymouth and Portland—one around its coast, and one along the South Dorset Downs, which reduces the path's length by 31.0 kilometres (19.3 mi). The path is the United Kingdom's longest national trail, at 1,014 kilometres (630 mi).
Weymouth is the largest town in the area, larger than the county town of Dorchester, which lies just to the north, and hence is a centre of activity for the nearby population. A steep ridge of chalk called the South Dorset Downs, locally known as The Ridgeway, separates Dorchester and Weymouth; they are less agricultural than the valleys in the centre and north of Dorset, but have dairy and arable farms. The nearest villages to Weymouth are part of the built-up area, including Wyke Regis, Chickerell and Preston.
Output:
What is the full name of the path whose length is reduced by the route around its coast and another along South Dorset Downs?
