Concept:Fix the known positions on the weekly schedule and then count the number of people between
J and
F.
Explanation:E has the exam on Friday, so
J has the exam on Saturday.
Only one person is between
E and
D, so
D must have the exam on Wednesday.
H has the exam immediately after
D, so
H is on Thursday.
F has the exam immediately before
D, so
F is on Tuesday.
Only two people are between
H and
G. If
G were on Sunday, then
I would be on Monday, but
I does not have the exam on Monday.
Therefore,
G is on Monday and
I is on Sunday.
Final arrangement:
Monday:
G, Tuesday:
F, Wednesday:
D, Thursday:
H, Friday:
E, Saturday:
J, Sunday:
I.
Between
J on Saturday and
F on Tuesday, the exams are on Wednesday, Thursday, and Friday.
So the people between them are
D,
H, and
E.
Answer:Three people have exams between
J and
F.
Correct option: C. Three.
