Here is the transcription of the image text with detailed explanations suitable for an educational context:

---

The image depicts a series of mathematical expressions related to set theory. Each line represents a proposition about the inclusion of elements or subsets in a set \( S \).

1. \( \{a, b, c\} \in S \)
   - This implies that the entire set \(\{a, b, c\}\) is considered an element of the set \( S \).

2. \( \{a, \{a, b, c\}\} \subseteq S \)
   - This means the set containing the element \( a \) and the subset \(\{a, b, c\}\) is a subset of \( S \).

3. \( a \in S \)
   - The element \( a \) is a member of the set \( S \).

4. \( \{a\} \subseteq S \)
   - The set containing only the element \( a \) is a subset of \( S \).

5. \( \{a, o, k\} \subseteq S \)
   - This indicates that the set \(\{a, o, k\}\) is a subset of \( S \).

6. \( \{a, b, c\} \subseteq S \)
   - The set \(\{a, b, c\}\) is a subset of \( S \), implying each element \( a, b, c \) is in \( S \).

7. \( \{\{a, b, c\}\} \subseteq S \)
   - The set consisting solely of the element which is itself a set \(\{a, b, c\}\) is a subset of \( S \).

8. \( \emptyset \subseteq S \)
   - The empty set is always a subset of any set, including \( S \).

Each checkbox on the left side is unmarked, possibly suggesting that these expressions could be part of a quiz or practice exercise where students are to verify whether each statement is true or false based on the characteristics of set \( S \).

**Set Theory Exercise**

Consider the set \( S = \{ a, o, k, \{ a, b, c \} \} \). Analyze and determine which of the following statements are true:

1. \(\{ a, o, k \} \in S\)

2. \( a \subseteq S \)

3. \(\emptyset \in S\)

4. \(\{ \emptyset \} \subseteq S\)

5. \(\{ o, k, a \} \subseteq S\)

6. \(\{ a, o, k, k \} \subseteq S\)

7. \( c \in S\)

8. \(\{ a \} \in S\) 

**Instructions:**  
Select the checkboxes corresponding to true statements based on the properties of sets and elements. This exercise helps in understanding the distinction between elements of a set and subsets of a set.
