Count the number of t's in the word Schism?
gpt
<thinking>Let's approach this step-by-step:
We should reason through this logically (CoT):

Step 1: How do we understand the challenge prompting me to do?
Calculate the occurrence of letter "t" in the string "Schism"

Step 2: Dissect the word.
S-C-H-I-U-M


Step 3: Oops, I made a mistake. The word I used above is incorrect. Let me correct that.
The correct word is "Schism", not "schium". I apologize for the error.

Step 4: Let's continue with the correct word. Spell out the word with numbered positions:

1. S
2. C
3. H
4. I
5. S
6. M

Step 5: Pinpoint the positions of the letter "t".
The letter "t" does not appear in the word.

Step 6: Sum up the letters.
M: 1, S: 2, I: 1, H: 1, C: 1

Step 7: Review the letters we counted.
The specified letter was "t" and there are 0 in all.

In summary:
The letter "t" occurs 0 times in "Schism".</thinking>
