Please answer the following question: What is the answer for the question: Smoke generators were set up in the north of where? from the following article ?  The arrival of the Manchester Ship Canal in 1894, and the subsequent development of the Trafford Park industrial estate in the north of the town – the first planned industrial estate in the world – had a substantial effect on Stretford's growth. The population in 1891 was 21,751, but by 1901 it had increased by 40% to 30,436 as people were drawn to the town by the promise of work in the new industries at Trafford Park.During the Second World War Trafford Park was largely turned over to the production of matériel, including the Avro Manchester heavy bomber, and the Rolls-Royce Merlin engines used to power both the Spitfire and the Lancaster.

A memorial to those residents who lost their lives in the bombing was erected in Stretford Cemetery in 1948, over the communal grave of the 17 unidentified people who were killed in the blitz of December 1940.Between 1972 and 1975, what is now a closed B&Q store in Great Stone Road was the 3,000-capacity Hardrock Theatre and Village Discothèque, hosting some of that period's major artists in their prime. Led Zeppelin, David Bowie, Bob Marley, Elton John, Hawkwind, Yes, Chaka Khan, Curved Air and Lou Reed were amongst those who appeared. Tangerine Dream was the last band to perform at the Hardrock, on 19 October 1975. In more recent years, Lancashire...
