TPO11 begging by nestlings - 英檢

※ 引述《cloudballoon (氣球雲)》之銘言：
: Paragraph 4：Given that predators can make it costly to beg for food, what benefit do begging
: nestlings derive from their communications? One possibility is that a noisy baby bird provides
: accurate signals of its real hunger and good health, making it worthwhile for the listening
: parent to give it food in a nest where several other offspring are usually available to be fed. If
: this hypothesis is true, then it follows that nestlings should adjust the intensity of their signals in
: relation to the signals produced by their nestmates, who are competing for parental attention.
: When experimentally deprived baby robins are placed in a nest with normally fed siblings, the
: hungry nestlings beg more loudly than usual—but so do their better-fed siblings, though not as
: loudly as the hungrier birds.
: Paragraph 5：If parent birds use begging intensity to direct food to healthy offspring capable of
: vigorous begging, then parents should make food delivery decisions on the basis of their offsprings
: calls. Indeed, if you take baby tree swallows out of a nest for an hour feeding half the set and starving
: the other half, when the birds are replaced in the nest, the starved youngsters beg more loudly than
: the fed birds, and the parent birds feed the active beggars more than those who beg less vigorously.
: 9. In paragraphs 4 and 5, what evidence supports the claim that the intensity of nestling
: begging calls is a good indicator of which offspring in a nest would most benefit from a feeding?
: ○ When placed in a nest with hungry robins, wellfed robins did not beg for food.
: ○ Among robin nestlings, the intensity of begging decreased the more the nestlings were fed.
: ○ Hungry tree swallow nestlings begged louder than well-fed nestlings in the same nest.
: ○ Hungry tree swallow nestlings continued to beg loudly until they were fed whereas well-fed
: nestlings soon stopped begging.
: ###想知道為何B不行 答案是C
: 10. It can be inferred from paragraphs 4 and 5 that parent songbirds normally do not feed
: ○ nestlings that are too weak to beg for food as vigorously as their nestmates
: ○ more than one hungry nestling during a single visit to the nest
: ○ offspring that were fed by the parents on the previous visit to the nest
: ○ nestlings that have been removed and then later put back into their nest
: ###想知道為何C不行 答案是A
: 懇請大大們幫忙解釋一下!!!

關於Q10 以下是個人淺見:
此題為推論題(是個"換句話說題")
題目的關鍵字是名詞子句的parent songbirds
回原文發現是考 在段落5的第一句話(假設語氣)的內容 If S+V, S+V.
作題時還是看主要子句的部份大意是 "parents 給食物基於叫聲"
逗號前的條件大意是 會哭餓大聲的幼鳥=有活力健康, then 食物給牠
關鍵字 intensity
所以依照原文此句 選A 且發現原文的vigorous是形容詞 選項A以副詞方式呈現
原文所講的intensity 以weak來表達 是有關於聲音強度
至於選項C 鎖定的句子 沒有表達這方面的訊息 所以應該是您定位到indeed的內容了
而覺得應該選跟"時間前後"有關的選項
