Answer 2

In which series of words is the unstressed checked vowel of the root missing?

The series of words in which the unstressed checked vowel of the root is missing is 4) разложение, расщепление, разъединение.

Explanation: In the Russian language, there are two types of vowels: checked vowels (а, о, у, э) and unchecked vowels (я, ё, ю, е, и). The checked vowels are pronounced with a shorter duration compared to the unchecked vowels.

In the given series of words, all the words have the prefix "раз-" added to the root. The prefix "раз-" indicates separation or division. In these words, the unstressed checked vowel of the root is missing. The original root words are "ложение," "щепление," and "ъединение." The checked vowel "о" in "ложение," "е" in "щепление," and "е" in "ъединение" are replaced by the unstressed vowel "е" in the derived words "разложение," "расщепление," and "разъединение."

Therefore, the correct answer is 4) разложение, расщепление, разъединение.
