Ken, after reading through the quesiton and thinking it through I arrived at the answer they give. They are trying to trick you into choosing syntax error. You'll find questions similar to this on the exams.

Subject: How do they get the answer?
I am taking the Self-Test software test for the SQL exam
and don't see how they get the answer to this problem.
They don't explain how it is arrived at.
Any help you can give me will be appreciated.
Thanks,
Ken Janusz, CPIM
----------------------------------
Examine the structure of the TEACHER table:
Name Null? Type
ID NOT NULL NUMBER(9)
SALARY NUMBER
(7,2)
SUBJECT_ID NOT NULL NUMBER(3)
SUBJECT_DESCRIPTION VARCHAR2(2)
There are 200 teachers and 15 subjects. Each subject is
taught
by at least 2 teachers.
Evaluate this PL/SQL block:
DECLARE
v_pct_raise number := 1.10;
BEGIN
UPDATE teacher
SET salary = salary * 1.10
WHERE subject_id IN (102, 105);
COMMIT;
END;
Which result will the PL/SQL block provide?
(A) Only two teachers will receive a 10% salary increase.
(B) All of the teachers will receive a 10% salary
increase.
(C) At least four teachers will receive a 10% salary
increase.
(D) A syntax error will occur.
Answer:
(C)
