Answer:
Your answer would be that a semicolon should be implemented after "hundred pounds".
Step-by-step explanation:
A semicolon is used to link in a single sentence two independent clauses that are closely related in thought. In this way, the two clauses are given equal rank or position. In the sentence above, the semicolon should be placed after the NP "hundred pounds". In this way, the first part of the clause will refer to elephant being alive, while the second one will refer to it being dead. The sentence would be as follows: alive, thee lephant was worth at least a hundred pounds; dead, he would only be worth the value of his tusks, five pounds, possibly.
