13. What happened The anticyclone pushing air downward-heated. Since the air when the ground is warmer than the highest created called inversion, leading to trap the hot smoke coming out of the chimneys. (13)

15. Apart from the smoke in their homes, the inversion phenomenon resulted trapped particulates and other pollutants from industries, so close to London and from farther away, the winds had relocated to the region. (15)

17. In combination with other meteorological parameters such as sunshine and moist winds, created a layer of smog 100-200 meters, and released tons of particulates, carbon dioxide, hydrochloric acid and fluorinated compounds, and an estimated 370 tons of sulfur dioxide were converted into 800 tons of sulfuric acid.

23. . Visibility was so limited that stopped all transport except the subway and even canceled screenings because of fog had penetrated through the halls. Most of the 12,000 victims who died in the deadly pollution were mainly children and the elderly. (23)
