Dragnet Verbal Reasoning Questions and Answers


Highly intelligent creatures, dolphins communicate with each other almost constantly. Although dolphins do not have their own language, experiments show that they can be taught to understand human sign language. Produced in the
dolphin’s respiratory system, high pitched whistles are used to raise alarm or convey emotional states. Every dolphin has a unique whistle, developed early in life. While some researchers believe that signature whistles enable individual
dolphins to identify each other, other scientists posit that the whistles simply alert other dolphins of their presence. Researchers have observed dolphins imitating each others’ whistle-suggesting that these creatures may be capable of vocal learning. Dolphins also emit a range of clicks, which emanate from the top of their head. Not only a method of sonar communication, these clicks also play a key role in hunting and navigation. The high-frequency clicks travel through the water and bounce off objects. The returning echo from the sound pulses allows a dolphin to judge the object’s distance and density with a high degree of accuracy. Scientist remain uncertain exactly how dolphin echolation works, with one theory being that they perceive the echo in their jaw. Bats use a similar echolation tool to
navigate


66)

Which two of these statements must be true?

(False) The passage suggest that dolphins and bats are similar animals
The passage does not suggest so, it however show that both dolphin and bats use Similar method of echolation

(True) It is possible for a human being to communicate with dolphin
Very true – since experiments show that dolphins can be taught to understand human signs

(True) Sonar pulses allow dolphins to distinguish between the thickness of different objects
The passage says in line 13 that the echo from the sound pulses allows dolphins to judge an object’s distance and DENSITY

(Cannot say) Dolphins are not the only species that use echolation to detect prey
This might be true but the passage does not tells us of any
67)

Which two of these statements must be true?

(True) Dolphins produce two types of sounds for the purpose of communication
The passage tells us of the high-pitched whistles used by dolphin to raise alarm or convey emotional states. It also tells us of the ability of dolphins to emit a range of clicks

(True) A dolphin uses echolation to communicate the location of prey to other dolphins
Very true – as seen in lines 11 to 15 of the passage

(Cannot say) Some scientist believe that dolphins have their own language
The passage clearly states that dolphins do not have a language of their own, however, it does not tell us if some scientist believe otherwise

(False) Dolphins do not vocalize exclusively for reasons of communication
The passage tells us of high-pitched whistles and a range of clicks made by dolphins, both of these are vocal sounds

The International Olympics Committee (IOC) is responsible for selecting a host city seven years prior to the games. During a rigorous selection process lasting two years, The IOC evaluates the candidates cities’ proposal and their ability to finance the games. Hosting the Olympics involves enormous expense- the 2008 Beijing Olympics, for Example, cost $43 billion. Expenditure includes the construction of stadia, infrastruction Improvements, and direct operating costs, such as athlete housing and security. Proponents believe that the outlay is justifiable, as the Olympics stimulate regeneration create jobs and increase tourism and media attention. They also bring unquantifiable “ benefits, such as prestige and ’’feel good factor”. However, detractors counter that the 17-day event rarely returns a profit, typically runs over budget, and leads to higher taxes for locals. Montreal, for example, took 30 years to pay off the debt it incurred by hosting the Winter Olympics in 1976. Furthermore, state of-the-art venues-such as Beijing’s $500 million Bird’s Nest-o often stand empty after the closing ceremonies finish. While The last three summer Olympics have left their host cities with huge debts, a successful Games can transform a city. Improvements made to Barcelona before the 1992 games created an enduring tourist destination


68)

Which of these two statements must be true?

(True) Some of the advantage bestowed upon the city cannot be easily calculated.
The passage states that “The events bring unquantifiable benefits, such as prestige and ’’feel good factor”

(True) Being an Olympics host city is a mixed blessing for the local community
This is true because the events bring benefits, such as prestige and “feel good factor” but can also cause some challenges like leading to higher taxes for the locals

(Cannot say) The IOC’s primary responsibility is the selection of the Olympics’ host cities
We were never told in the passage if this is their PRIMARY role

(Cannot say) The Games’ seven-year selection process involves detailed analysis
Nothing was said about the Games’ seven-year selection process involving detailed analysis, we were only told of a rigorous selection process lasting two years
69)

(Cannot say) The IOC takes into account whether potential host cities would benefit from regeneration
Line 3 says “The IOC evaluates the candidates’ cities’ proposal and their ability to finance the games” it says nothing about the above statement.
