You want to have several tables:
Teachers:

ID              IDENTITY or GUID
Name            NVARCHAR()

Subjects:

ID              IDENTITY or GUID
Name            NVARCHAR()

Papers:

ID              IDENTITY or GUID
Name            NVARCHAR()
SubmitDate      DATE or DATETIME
TeacherID       INT or GUID, Foreign key to Teachers.ID
SubjectID         INT or GUID, Foreign key to Subjects.ID

Questions:

ID              IDENTITY or GUID
PaperID         INT or GUID, Foreign key to Papers.ID
...

You then access them using SQL JOIN statements:

SQL

SELECT q.* FROM Questions q
JOIN Papers p ON q.PaperID = p.ID
WHERE p.Name LIKE '%Transdimensional Physics%'
