In the reading passage it is mentioned that researchers believe that nature and nurture both play a great role in the development of personality of twins. They discuss both identical (monozygotic) and fraternal (dizygotic) twins. And researchers debate that which aspect nature or inheritance more significant for twins. But in the listening passage the professor emhasizes that she does not believe the usefulness of this research. She mentions that there are some assumptions that are questionable. In the reading passage it is underlined that identical twins have more similiraties than others. If even they will be seperated different environment and grow seperately they show many simiralities. It means that genetics plays a great role on these twins. Moreover, it is also argued that with the help of this theory they can calculate the physical desorders or understanding of music or intellectual levels of twins. But in the listening passage the professor mentions the similar environment problem. She debates that both identical and fraternal twins live in the same life conditions. They do the same activities for example the same school activities. So the professor highlightes that if the identical twins want to eat the same icecream or to wear the same clothes by themselves it can be the result of heredity. On the other hand the professor metions that everybody around the identical twins even their family members suggest them the same things or activities. Everybody wants to see them in the same situation. Thus the professor mentions that because of the pressure of the environment the personality of identical twins developes similarly. In this situation environmental factors are more improtant than genetic factors.
Hi, your grammar is good, but I sort of lost track of your structure or the points you were trying to make around the middle of your essay - after “intellectual levels”. You recovered near the end, so I was able to figure out what you were trying to say.
