Questions 1-10

Useful strategy: identifying words with a similar 
meaning
1  1  B Our company = Here at Household Electronics
  spent large sums of money = invested heavily
  cannot find any evidence = shows no connection 
between
  our products = the screens we manufacture
  harmful to health = headaches, eye problems or 
other such issues
 
A is wrong because Olivia Downey works at a 
laboratory, not a company, and her research has 
found some evidence that screens may cause 
health problems. 
2  A The results of the research = the findings
  not reliable = invalid
  sample = subjects
  the study = the experiment
  too small = so few
 
B is wrong because Professor Lannighan explains 
why a small sample size was used, but does not 
mention the results of the research. 
3  A possible to change = be able to alter
  public opinion = the views of ordinary people
  but it will only happen = If
  facts and statistics = data
  widely available = broad range of different media
 
B is wrong because Mei Tan is talking about a past 
event, not a future possibility. 
4  B The research done so far = the studies to date
  encouraging = some very positive results
  too early = until more work has been completed
  firm conclusions = know for sure
 
A is wrong because Marie Dubois talks about a 
‘variety of results’, not ‘encouraging’ results, and 
she speculates that future research may require 
an ‘alternative approach’.
