Answer:
A,B and C are important factors used as criticism for the Turkish accession to the EU. However only option D)The fact that Turkey is a predominantly muslim nation. Has not been used as a reason to criticize the accession of Turkey to the EU.
Explanation:
First of all, only a small portion of turkey is inside Europe's geographical territory, while the vast majority of its territory forms part of Asia and the Middle East. That has been a major factor proposed by many European countries.
Second, B) Turkey has no secured the rights of freedom of expression. The political party in power has been very harsh and aggressive to the opposition, majorly against journalists, critics, and media. One of these examples is the most recent coup d'etat in which reporters and journalists were targeted.
Third, C) has not formally recognized the Armenian genocide. It has not and many countries like Denmark and Germany have faced them with proofs, but they never bring solid fundamentals to their statement.
The fourth d) is a predominantly Muslim Nation. Which is false because even though there is a presence of racism in almost all European countries, it has been executed by a small part of the population, and not the government. French, German, Swedish and many other countries' governments have shown support to the Muslim population.
