The first reaction involves a ketone reacting with an acrylate in the presence of a strong base, while the second reaction involves a nitro compound reacting with a nitrile under basic conditions. To determine the major products, we must consider steric hindrance and the stability of the resulting compounds. The goal is to select the correct product candidates from the provided options based on these considerations."}
