Read the text and answer the question by selecting all the correct responses. More than one response is correct.

The impact of a meteorite released a huge amount of energy, excavating a crater regarding double as large as the lunar crater Tycho. The explosion lifted about a hundred trillion tons of dust into the atmosphere, as will be determined by measuring the thickness of the sediment layer formed when this dust settled to the surface. Such an amount of material would have blocked the daylight completely from reaching the surface, plunging Earth into an amount of cold and darkness that lasted at least several months. The explosion additionally calculated to have produced vast quantities of nitric acid and melted rock that sprayed out over much of Earth, starting widespread fires that must have consumed most terrestrial forests and grassland. Presumably, those environmental disasters might are answerable for the mass extinction, including the death of the dinosaurs.

Q. According to the paragraph, which of the following statements are true of the impact at the end of the Cretaceous period:

(A) A large amount of dust blocked sunlight from Earth.
(B) Earth became cold and dark for several months.
(C) New elements were formed in Earth’s crust.
