Question

what did the scientists at the conference say about James 's sums

Answer 1

The scientist at the conference checked and rechecked James calculations with the latest observations of Coment Dutta. They said James calculations were correct. There was no escape from the direct hit James had predicted.

Answer 2

Answer :-

The experts and scientists checked and rechecked James Forsyth’s calculation with the latest observations of Comet Dutta. They found that his calculations and sums were correct that a comet might collide with Earth soon. However, there was a small chance that that the comet might just graze the atmosphere of the Earth and not collide with it. But this slight intermission was not a reassurance for not taking an action.
