Reading 26. Hedge Fund Strategies (2020 CFAI curriculum)

EOC question 1 - Asks you to determine and justify among 4 strategies. On the justification part, the answer goes on to describe the strategies. I though the first sentence is enough justification?

So my question - Is this how you answer a similar question in the exam or this is just to help candidates to understand better? I am repeating candidate, so I am trying to master AM exam answering technique.

It’s for understanding.

You do not have to define the strategy unless the question says " Define the strategy." Define is a CFA Institute command word.
