Which of the following side-by-side reasoning is joint reasoning?

3.3.1 Questions appendix, passage 29.

3.3.2 There are in fact good reasons why one would not expect blood cholesterol to vary with diet. First, the liver manufactures three or four times as much cholesterol as is normally ingested.
