The answer is:
______________
"no error".
________________
The comma is correctly placed before the conjunction "for"; and in this instance in which the word, "for", is used, a comma is necessary. No other part of the sentence needs—or requires—a comma, and there are no commas that are placed unnecessarily.
________________________________
As a side note, I would recommend that the first letter of the first word in the sentence: "Abbey", be capitalized, because:
________________________________
1) It is the first word at the beginning of the sentence; and:
2) It is someone's name, which is a proper noun.
__________________
I also recommend placing a "period" at the end of the sentence.

To read:
___________
<span>Abbey is most interested in learning how to mount her horse, for she already knows several things about dressage.
____________________________</span>
Which of the following statements best summarizes the content of the two sources?

Bahas menteri ke 3 adalah sama seperti menteri pertama dan kedua, yang berlainan hanyalah isi teks. SELALUNYA, teks penggulungan tidak boleh dibacakan oleh menteri ketiga (hanya menteri pertama atau kedua sahaja). Seperti menteri kedua, menteri ketiga WAJIB membalas celahan pihak pembangkang. Jika sekiranya menteri ketiga tidak membahas celahan pihak pembangkang, ini bermakna menteri ketiga bersetuju dengan dengan apa yang pihak pembangkang telah utarakan (ini akan menyebabkan pihak kerajaan kalah dalam perbahasan tersebut).
