The Shannon Dolphin and Wildlife Foundation (SDWF)1 has been studying a group of up to 120 bottle-nose dolphins in the River Shannon2 using vocalisations collected on a computer in a cow shed3 near the River Shannon.
As part of a research project, student Ronan Hickey digitised and analysed a total of 1,882 whistles from the Irish dolphins and those4 from the Welsh dolphins on a computer and separated them into six fundamental whistle types and 32 different categories5. Of the categories, he found most6 （大多数）were used by （被...使用）both sets of （来自Irish和Welsh的）dolphins7 -- but eight were only heard （仅仅被听见）from the Irish dolphins.

As part of （部分的）a research（研究） project（计划）, student Ronan Hickey digitised （使数字化）and analyzed（分析） a total（总数） of 1,882 whistles（鸣叫声， 口哨声， 汽笛声） from the Irish（爱尔兰） dolphins and those from the Welsh（威尔士的） dolphins on a computer and separated them into（把...分成...） six fundamental whistle types (基本鸣叫类型) and 32 different（不同的） categories(种类) .

"We are building up（正在建立）a catalogue（目录） of the different（不同的） whistle types（类型） they use and trying to associate them with（把...和...联系起来） behavior（行为） like（例如） foraging（觅食）, resting（休息）, socialising（社交） and the communications of groups with calves（牛犊）," project（项目） leader Simon Berrow said. "Essentially（实质上， 实际上） we are building up what is like（象） a dictionary of words （字典）they use or sounds they make."
Berrow, a marine biologist, said the dolphins' clicks are used to find their way around and locate prey. The whistles are communications。 "They do a whole range of other sounds like barks, groans and a kind of gunshot," he said. "The gunshot is an intense pulse of sound. Sperm whales use it to stun their prey.
"When I first heard it I was surprised as I thought sperm whales were the only species who used it. We can speculate the dolphins are using it for the same reason as the sperm whales," Berrow said.
References8 in local legend indicate there have been dolphins in the Shannon estuary for generations and they may even have been resident there as far back as the 6th century9.
They are regularly seen by passengers on the Shannon ferry and an estimated 25,000 tourists every year take special sightseeing tours on local boats to visit them.
短文第四段第一句说科学家正在设法将啸声与海豚的行为特性联系起来，由此可推断出这也包括成年海豚与小海豚之间的联络这种行为。题句的意思与原句的意思相符，所以答案是 A。
5. Sperm whales（巨头鲸） can produce（产生）stronger（更强的） ultrasonic waves （超声波）to kill（杀死） their prey（猎物） than dolphins（企鹅）.
