此句取自p. 106 of 11.2021 NATIONAL GEOGRAPHIC
Rather than a gaggle of tourists, out 【□】 Tom Hart, a penguin biologist from Oxford University, and several other scientists returning to the Antarctic Peninsula.
請問空格內填入下列何者為最佳？
(1)climbing
(2)climb
(3)climbs
(4)以上皆可
這句話採用倒裝，主詞是Tom Hart and several other scientists，所以是複數，動詞用原形，選(2)。
原句：Tom Hart and several other scientists climb out.
採倒裝是為了以同位語(a penguin biologist from Oxford University)說明Tom Hart是什麼人，同時避免句子頭重腳輕(修辭學的範疇)。
