In this passage about the changing experiences of life, choose the correct word to complete the sentence "Some ______ are pleasant and joyful while others are full of sorrow and pain."

Introduction / Context:
This multiple choice English question continues a cloze passage describing different kinds of events in life. The sentence to be completed is "Some ______ are pleasant and joyful while others are full of sorrow and pain." We need to choose the noun that naturally fits with the rest of the passage and matches the theme of life experiences.

Given Data / Assumptions:

The wider passage talks about life being full of many types of experiences.
One sentence states that some things are pleasant and joyful and others are full of sorrow and pain.
The blank must be filled with a plural noun that can logically be described as pleasant or painful.
We assume a general reading comprehension and vocabulary context based on standard English usage in exams.

Concept / Approach:
The key is to match the blank with the overall theme and with the earlier sentence, which mentions "types of experiences". A good cloze solver checks for semantic consistency, grammatical number, and collocation. The noun should logically refer to things that can be pleasant or painful, and it should connect back to "types of experiences" at the start of the passage. This immediately suggests that the correct word is "experiences".

Step-by-Step Solution:
Step 1: Read the given sentence: "Some ______ are pleasant and joyful while others are full of sorrow and pain." Step 2: Recall the first line of the passage: "Life is full of many types of experiences." Step 3: Observe that the word directly connected with the idea of life events is "experiences". It is plural and can naturally be pleasant or painful. Step 4: Now test each option in the blank: "Some tenderizes", "Some rituals", "Some customs", "Some experiences", and "Some moments". Only "experiences" perfectly repeats and develops the central idea of the passage. Step 5: Confirm that "experiences" maintains both grammatical correctness and thematic unity with the rest of the passage.

Verification / Alternative check:
If we read the full set of related sentences, the passage says that life is full of different types of experiences, some of which are pleasant and joyful while others involve sorrow and pain. Replacing the blank with "experiences" yields the sentence "Some experiences are pleasant and joyful while others are full of sorrow and pain." This sounds completely natural and reinforces the key idea. None of the other options provide this smooth connection to the main theme, so our answer is verified.

Why Other Options Are Wrong:

"tenderizes": This word is usually used for softening meat or food and does not make sense when followed by "are pleasant and joyful". It is also grammatically strange after "Some".
"rituals": Rituals can be joyful or solemn, but the passage is clearly discussing "types of experiences" in general, not religious or cultural acts specifically.
"customs": Customs refer to habitual practices of a community. Again, the passage is talking about events and feelings in life, not only cultural practices.
"moments": While "moments" can be pleasant or painful, the passage already introduced "types of experiences". Using "experiences" for the blank creates a clear repetition and unity, which is typical in cloze passages. "Moments" does not link as strongly to that earlier phrase.

Common Pitfalls:
A common mistake is to pick any word that can be pleasant or painful without reading the whole passage. For example, a candidate may choose "rituals" or "moments" because they appear meaningful in isolation. However, cloze tests reward careful attention to thematic links. Another pitfall is ignoring the earlier line about "types of experiences". The best practice is always to read both backward and forward around the blank before deciding.

Final Answer:
The correct word to complete the sentence is "experiences".
