PP test1 Listening Q130-140

[molecular]

版主大人, 我知道之前已經有一篇討論了, 可是那篇文章沒有貼出全文,
再加上版主的回應是請他遵守版規發文, 我記得這樣沒有遵守版規的發文, 是會被鎖文才對, 因為作者都一直沒有更正過來
而且我也不知道怎麼接下去問才好, 因此暫時重起爐灶, 如果版主覺得不行的話, 再跟我講, 鎖文也沒關係
Thanks
130-134 A lecture on an ornithology class:
You know, it’s a kind of fashionable among students of birds just study rare and exhausted species, especially endangered ones like golden eagles or sparkle owls. But I often think that everyday birds, birds that are really part of our lives, are simply overlooked. So I likely spend some time talking about very common birds “black crows”. It might surprise you, you know, that crows are among the most challenge birds to observing study. First of all, they look alike. Picking out one or several individual crows in a flock and finding them again later is almost impossible. People studying larger animals can put some kind of mark on them, so they can tell them apart. Well, you can trap large animals like a bear in an immobilized or tranquilized gun, then it is easy to put a tag on it. But try doing that to a crow, you probably kill it. Secondly, crows are highly intelligent survivors. They adapt easily to wildly varying situations. This adds to the difficulty of studying in them, because they pick up so many individual life habits. So you can never be sure about any conclusion you reach about crows from observing them and applies the whole species or just those particular crows you’ve been watching. One general observation about crows that can be made in the reasonable degree of certainty is that in the last forty years more and more crows have been found living in large cities. They are attracted by people, who produce enormous amount of garbage and leave it places that crows can easily get to. It makes distances they must have trouble to hunt a large shorter.

想請問最後一句紅字的話是什麼意思? Thanks

script錯了，應該是It makes the distances they must travel to hunt a lot shorter.
