Consider the following profiles of student proficiencies:
(i) $B$ and $E$ are good in Dramatics and Computer Science.
(ii) $A$ and $B$ are good in Computer Science and Physics.
(iii) $A$, $D$ and $C$ are good in Physics and History.
(iv) $C$ and $A$ are good in Physics and Mathematics.
(v) $D$ and $E$ are good in History and Dramatics.

Who is good in Physics, History, and Dramatics?

Let us trace the requirements for Physics, History, and Dramatics:
* From statement (iii), $A$ and $D$ are good in Physics and History.
* From statement (v), $D$ and $E$ are good in History and Dramatics.
* Intersecting these: $D$ is common to both statements. $D$ is good in Physics and History (from iii), and $D$ is also good in History and Dramatics (from v).
Therefore, $D$ is proficient in Physics, History, and Dramatics.
