What is the answer to the puzzle?

The question presented in the image is a puzzle. The text on the image reads: "Вчительський стіл. Підказка З.Пе. Перший слайд називається... (4 буква відгаданого слова є 1 буквою ключа)" which translates to "Teacher's desk. Hint 3.Pe. The first slide is called... (the 4th letter of the guessed word is the 1st letter of the key)".

Based on the clue that the word has 4 letters, and knowing that the first slide of a presentation is usually an introduction, the answer is likely "Тема" (Tema), which means "Theme" in English.

Answer: Тема
