Dragnet Verbal Reasoning Questions and Answers


Chronic Fatigue Syndrome (CFS) is the widespread name for a disorder that isalso called Myalgic Encephalomyelitis (ME), but many sufferers object to the name CFS on grounds that it is does not reflect the severity of the illness. While profound fatigue is one symptom of this debilitating condition, there are many others, including muscle pain, headaches, and cognitive difficulties. Its nomenclature is not the only controversial aspect of CFS. Although an estimated 17 million people worldwide have CFS, its cause is unknown and a diagnostic test does not exist. Doctors must first rule out other conditions that share CFS’s symptoms. As there is no cure for CFS, treatment tends to focus on alleviating symptoms, which can range from mild to severe. Despite the World Heath Organisation classifying CFS as a neurological disease, there is much disagreement within the medical community. Some scientists believe that CFS originates from a virus, others argue that it stems from genetic predisposition, while still others believe that it is a psychiatric condition. Because of continuing scepticism about CFS, patients welcomed a 2009 study that linked CFS and a XMRV retrovirus. What at first appeared to be a major scientific breakthrough, however, was not proven by further research – and XMRV is now thought to be a lab contaminant.


81)

Which of these two statements must be true?

(True) CFS’s symptoms are also attributable to other illness
Very true – as seen in line 8 and 9 of the passage

(True) The exact number of CFS sufferers is unknown
No exact figure was given but an estimation of 17 million people worldwide

(False)The cure for CFS is to alleviate symptoms
The passage says there is no cure for CFS, however you can only treat to alleviate symptoms not to cure

(Cannot say) CFS stems from genetic predisposition
This is not a fact from the passage but the belief of some scientist
82)

Which of these two statements must be true?

(True) A 2009 study linking CFS with a retrovirus has now been discredited
For it not to be proven by further research, it means that it has been discredited

(True) World Health Organisation classify CFS as a neurological disease
Very true – as seen in line 11

(False) Scientists believe that CFS originates from a virus
Not all believe so – as seen in line 12 and 13 of the passage

(Cannot say)The Writer believes that CFS is a psychiatric condition
The writer never gave any opinion of CFS as a psychiatric condition, it was actually some scientist that believe this – line 14 of the passage
83)

Which of these two statements must be true?

(Cannot say) CFS’s symptoms lack consensus within the medical community
The passage says nothing about this, the area where there was disagreement within the medical community was in the classification of CFS as a neurological disease

(Cannot say)Many patients believe the name Myalgic Encephalomyelitis trivialises the condition
We were not told in the passage the reaction of patients to the name Myalgic encephalomyelitis, it was actually the CFS name that sufferers reacted to

(True)A symptom of CFS is profound fatigue
Very true – as seen in line 3 of the passage

(True)There are more than two controversies to CFS
Yes, this can be seen in lines 3 to 5, and line 7 to 8

Oil sands are most commonly found in Venezuela’s Orinoco Basin and Alberta, Canada. Modern technology has made the extraction of crude bitumen, or unconventional oil, from these oil sands much easier. The crude oil that is
extracted from traditional oil wells is a free-flowing mixture of hydrocarbons, whereas oil sands yield a highly viscous form of petroleum. Increasing world demand for oil and higher petrol prices have made the economic viability of
extracting oil sands approach that of conventional oil. Oil sands have been described as one of the dirtiest sources of fuel. Compared to conventional oil, four times the amount of greenhouse gases are generated from the extraction of bitumen from oil sands. Additionally there is an impact on the local environment. Tailing ponds of toxic waste are created whenever the tar sands are washed with water. Proponents of oil sands development point to the land that has already been reclaimed following oil sands development. Also, that there will be considerably less surface impact once technology innovations have allowed oil sand reserves to be drilled rather than mined.


84)

Which of these two statements must be true?

(Cannot say) Oil sand is the dirtiest sources of fuel
Very true – as seen in the second paragraph line one

(True) Technology has made oil extraction easier
Very true – as seen inthe second line

(False) Conventional oil generate four times more green house gases
The passage tells us it is the other way round – as seen in the first three lines of the second paragraph

(True) Alberta is located in Canada
Very true – as seen in the first line of the passage
85)

Which of these two statements must be true?

(True) It is more expensive to extract oil sands
Very true - as seen in line 6 and 7

(True) There is less economic viability for oil sands
Since it is more expensive to extract, there will less economic viability

(Cannot say) Lands are reclaimed by oil sand development
This is not a stated fact in the passage, it is just a claim from proponents of oil sands

(Cannot say) Technology has reduced surface impact
This cannot be asserted since it is a matter of probability – the passage says that there will
be considerably less surface impact once technology innovations have allowed oil sand
reserves to be drilled rather than mined.
