Final answer:
Pinto is the correct answer as it refers to both a type of bean and a horse color pattern, unlike soybeans, lima beans, and mare which do not have this dual reference.
Step-by-step explanation:
The answer to the question is Pinto, which refers to both a type of bean and a coloring pattern of horses. Phaseolus vulgaris is the scientific name for pinto beans, which alongside black beans and kidney beans, belong to the common bean category. Pinto beans are often eaten whole, or mashed and then refried. The word 'pinto' in horses refers to a coat pattern that features large patches of white and any other color. The key differentiator in identifying 'Pinto' as the answer is that soybeans, under the scientific name Glycine max, are distinct in their applications and don't share the 'horse' association, and 'Mare' is solely a term for an adult female horse. Lima beans, also known as butter beans, come from the species Phaseolus lunatus and are not associated with horses.
