Please explain* I want to understand how to work out each part

Question 2. Cost-effective reserve site selection Suppose you are in charge of reserve site selection (RSS) to conserve species. The objective is to maximize the number of unique species conserved. There are five patches to choose from, numbered 1-5. When a patch is selected as a reserve, assume that the species it contains (e.g. species A, B, etc.) are conserved with certainty. A given patch contains a given species only if the corresponding cell holds a "1". Suppose that your budget allows for the selection of only two sites. Species A B C D E F G H 1 1 1 1 1 1 1 Patch 3 1 1 1 1 1 1 1 1 Consider the three strategies below for RSS. For each one, (1) briefly explain the strategy (one sentence); (2) identify the two patches that would be selected under this approach; and state the number of unique species conserved. (Note that there may be more than one right answer to the "Identify patches" question.) a) hotspots Explain: Identify patches: State # unique species conserved: b) greedy algorithm: Explain: Identify patches: State # unique species conserved: c) cost-effective: Explain: Identify patches: State # unique species conserved
