=>ANSWER: NOT GIVEN

1. Epigenetic processes are different from both genetic and environmental processes

Keywords: Epigenetic processes, genetic, environmental

In paragraph 6, the writer states that “….nature and nurture are not the only elemental forces at work. According to a recent field called epigenetics, there is a third factor also in play, one that in some cases serves as a bridge between the environment and our genes.”

• 
  genetic and environmental processes~nature and nurture
  

=>ANSWER: TRUE

1. invented a term used to distinguish two factors affecting human characteristics.

Keywords: term, distinguish, characteristics

In paragraph 4, the writer explains that “The idea of using twins to measure the influence of heredity dates back to 1875, when the English scientist Francis Galton first suggested the approach (and coined the phrase „nature and nurture‟)”

• 
  invented=coined
  

=>ANSWER: A

1. expressed the view that the study of epigenetics will increase our knowledge Keywords: study of epigenetics, increase our knowledge

In paragraph 12, the geneticist “Reed adds, the latest work in epigenetics promises to take our understanding even further”.

• 
  study of epigenetics=work in epigenetics
  
• 
  increase our knowledge~take our understanding even further
  

=>ANSWER: C

1. developed a mathematical method of measuring genetic influences.

Keywords: mathematical method, measuring

In paragraph 5, the writer says that “Bouchard and his colleagues used this mountain of data to identify how far twins were affected by their genetic makeup. The key to their approach was a statistical concept called heritability. In broad terms, the heritability of a trait measures the extent to which

differences among embers of a population can be explained by differences in their genetics”.
