Given this, I'll have to categorize it to the most specific, relevant one; however, there appears to be a language barrier here. After some research and translation, I assume EKPSS is related to educational institutions (education authorities) or a teaching profession and ILKOGRETIM is related to primary education, and then it appears to be targeted at mathematics in 'Ogrencimlikki Girisim', or math teacher. Based on the translation, I think 'Science & Research' is the closest match with 'Education & Learning' being an available choice; however, a choice might not perfectly fit. The most specific category: Science & Research

None of the given categories directly relate to the phrase "Earth Quake" identifier. If considering that "Earthquake" refers to a natural disaster, I would suggest the categories either "Science & Research" or "Old / Historical" are too specific / least suitable category.

Physical Science - This would most naturally fit into 'Science & Research'.

Earth and Space Science, specifically Gaia refers to Greek mythology's Gaea, associated with the planet Earth, a category that closely aligns with "Science & Research".
