Practice 1 — Making Your Own SCP
Create 3 original propositions for each form (A, E, I, O).
Each proposition must relate to ==student clubs==, and the predicate must be a noun.
A. Form (A) — Universal Affirmative
Structure: All S are P.
Example: All SIIT students are learners who passed the application process.
Your Propositions
A1. All book-club members are people who like reading.
A2. All coding-club core team members are programmers.
A3. All music-club officers are students with leadership roles.
B. Form (E) — Universal Negative
Structure: No S are P.
Example: No project proposals are plans that were rejected.
Your Propositions
B1. No teaching classes are events that are held during the examination period.
B2. No club activities are events that occur during final exams.
B3. No environmental-club meetings are gatherings without sustainability goals.
C. Form (I) — Particular Affirmative
Structure: Some S are P.
Example: Some borrowed books are reading materials that are returned.
Your Propositions
C1. Some club members are students from the engineering faculty.
C2. Some members from the Peanut club are people who love temples.
C3. Some debate-club participants are students with strong public-speaking skills.
D. Form (O) — Particular Negative

Your Propositions
D1. Some football-club players are not athletes who attend every training session.
D2. Some members of the faculty club are not instructors who teach classes.
D3. Some art-club members are not students who draw as their main hobby.
Practice 2 — Identifying the SCP Form
Identify the SCP form (A, E, I, or O).
Circle the copula ("are", "are not") to help you locate S and P.

|---|---|---|
| 1 | All problems in the morning are things that were fixed. | A |
| 2 | Some titles that I stream are movies that are not behind a paywall. | I |
| 3 | All late submissions are things that were given a point deduction. | A |
| 4 | Some courses this semester are online classes. | I |
| 5 | Some laws on marijuana are things that are debated. | I |
| 6 | No prison guards are security personnel who sleep at work. | E |
| 7 | All of my exes are people in the past. | A |
