Answer to Question 1

B

Answer to Question 2

The vagus nerve carries parasympathetic preganglionic fibers to many organs within the ventral cavity, including the digestive organs. It stimulates gastric motility and secretion of acid and enzymes. Removing the vagus innervation will eliminate parasympathetic stimulation, leaving only sympathetic innervation, which is inhibitory. This procedure will thus greatly reduce gastric activity. Hormonal stimulation will remain but higher centers will no longer influence secretion of gastric juice.
