@lzagrodnik The final paragraph is the author's opinion which E covers it.

"New evidence has been found that favors the view that LHB was widespread" which is on the first sentence of the final paragraph.

"More evidence needs to be gathered" which is towards the last sentence of the final paragraph.

@Lylas123 I am going to try this. I did well on the weakening questions but I am still confused on strengthening questions.
