The interpretation of the negative entries in matrix B - A is (c) there are more endangered/threatened species of this type in the United States than all other countries combined

<h3>How to interpret the meaning of the negative entries in matrix B - A?</h3>

The complete question is added as an attachment

From the attached question, we have the following parameters

Matrix A = The numbers of some species of threatened and endangered wildlife in the United States
Matrix B = The numbers of some species of threatened and endangered wildlife in foreign countries

The value of matrix B - A means:

The number of some species of threatened and endangered wildlife in the United Stated SUBTRACTED from the numbers of some species of threatened and endangered wildlife in foreign countries

So, when there are negative entries in matrix B - A;

It means that A > B

i.e. there are more endangered/threatened species of this type in the United States than all other countries combined

Hence, the interpretation of the negative entries in matrix B - A is (c)
