Question
If the student works hard in philosophy, first class will be obtained.
The student will do well in philosophy.
Therefore, the student will receive first class.

Answer

Hint: $P =$ Student will work hard in philosophy.
$Q =$ The student will receive first class.
Symbolic representation of the argument:
$P\rightarrow Q$
$P$
$\therefore Q$
Combining the two bases of this argument as a whole, the argument will be as follows:
$(P\rightarrow Q) \& P$
$\therefore Q$
Truth Table:
  Support Statement The resulting statement
  $1$ $2$ $3$ $4$ $5$
$P$ $Q$ $P\rightarrow Q$ $(P \rightarrow Q) \&  P$ $Q$
$1$ $T$ $T$ $T$ $T^*$ $T^*$
$2$ $T$ $F$ $F$ $F$ $F$
$3$ $F$ $T$ $T$ $F$ $T$
$4$ $F$ $F$ $T$ $F$ $F$
  $1, 2(\rightarrow)$ $3, 1 (\&)$ As $2$
Judgment of the validity of the argument: A total of five columns have been formed in the above fact sheet. In which the column no.$ 4th$ base statement and column no.$ 5$ is the representation of the result statement. Out of the total four rows of the truth table, only rows. The base statement in $1$ is truth $‘T’$ and the resulting statement in the same row is also truth $‘T’$ Hence this argument is standard.
