evidence

Explanation:

An essay in which a student makes a defense of his/her point of view may be marked by scientific evidence that has already been established earlier. This is one way to ensure that your work does not contain inconsistencies, the evidence works as a way of proving the thesis that the student is advocating.

For example, if the student is arguing that there is a relationship between alcohol intake and traffic accidents, he or she may seek official statistical evidence to support his or her thesis.

answer

answer: a: they can affect the author’s perspective and in turn the theme and purpose for the writing.

the author's background and time period greatly affect the text that the author produces. this is because we are all a reflection of our time period and background. depending on where and when we were born, we will find some questions more important than others. for example, if we are a wealthy person born in medieval times, we will most likely be interested in courtly love and stories of knights and honour. however, if we are born in the 20th century in africa, we might instead focus on colonialism and its effects on the newly liberated countries. the theme and the purpose of writing are both affected by these conditions.
