Task: Question Generation
Input (English): Passage: In his 1924 publication dealing with Kent, the archaeologist O. G. S. Crawford, then working as the archaeological officer for the Ordnance Survey, listed the Coldrum Stones alongside the other Medway Megaliths. In 1926, the Coldrum Stones were given to The National Trust, which dedicated it as a memorial to the Kentish prehistorian Benjamin Harrison. A plaque was erected to mark this, which erroneously termed the monument a stone circle; in 1953, the archaeologist Leslie Grinsell expressed the view that "it is hoped that this error may be rectified in the near future". Still owned by the Trust, the site is open to visitors all year round, free of charge. On their website, the Trust advises visitors to look for "stunning views from the top of the barrow". John H. Evans characterised the site as "the most impressive" of the Medway Megaliths, while Grinsell described it as "the finest and most complete" of the group.Among the Pagans who use the Coldrum Stones for their ritual activities, there is general satisfaction with the Trust's management of the site, although some frustration at the poor access for disabled visitors. A patch of scorched earth exists on the grass in the centre of the monument, perhaps used by Pagans as well as non-Pagans, and the Trust warden responsible for the site has decided to leave it there rather than seeding it over, in order to encourage any who do light fires to do so in the same spot rather than nearer to the stones themselves. The site also faces a problem from litter left by visitors, although Pagans who regularly visit the site clean this up.
Output (English): What is the name of the site characterized by Evans as "the most impressive" of the broader group?
