Please choose the correct ending to complete the given sentence: Pets and Animals: [header] How to train a rabbit [title] Understand what motivates your rabbit. [step] Rabbits are very intelligent and eagerly respond to incentives. This means that strong punishment, such as spanking or yelling at a rabbit, won't make it more cooperative.

Ending1: [substeps] Even a scolding can be irresistible for rabbits. Direct punishment can help keep your rabbit bored. Ending2: If you use incentives correctly, however, most rabbits will respond accordingly. [substeps] Food is generally used as motivator, but toys may also be a reward for your rabbit. Ending3: [substeps] Punishing a rabbit does not always mean he should be rewarded. If your rabbit has just done something good, making your dog happy can generally help your dog get ahead at home. Ending4: Punishment this way will only make the rabbit more compliant. Undesirable behavior simply suggests that the rabbit is quite timid and doesn't enjoy being petted by the owner.
