All people should be expected to react in the same manner to the same stimuli.是 错的 还是 对的 呢

All people should be expected to react in the same manner to the same stimuli.
修正建议:
(1)"People are expected to react in the same manner to the (same) stimuli."
(2) "Everyone is expected to react in the same manner to the (same) stimuli.
注:
(a)"the same stimuli" 的 "same" 可以删; "the stimuli" 已足够.
(b) "stimuli"是复数; "stimulus" 是单数.
