Question

which animal is not omnivor? 鼠(shǔ) 马(mǎ) 猪(zhū) 鸡(jī)

Explanation:

To determine which animal is not an omnivore, we analyze the diet of each:

• 鼠 (shǔ, mouse): Omnivore (eats plants and animals).
• 马 (mǎ, horse): Herbivore (eats only plants).
• 猪 (zhū, pig): Omnivore (eats plants and animals).
• 鸡 (jī, chicken): Omnivore (eats grains, insects, etc.).

Among these, the horse (马) is a herbivore, not an omnivore.
