Answers

Answer 1

When used as parameters, the type of variable that allows a function to access the parameter's original argument is D) reference.

A reference variable is a variable that is used to refer to a memory location. The reference variable is declared with an ampersand in C++ programming. It's often utilized to refer to the same object or variable by a variety of names. A reference variable is an alias for the variable to which it is assigned. This means that modifying the reference variable would modify the initial variable.

Reference variables are utilized in a variety of scenarios, including function arguments, function returns, and assignments. It provides a way for programmers to make more efficient code by avoiding the cost of copying large objects.

The greatest amount of oil pollution comes from the large oil tanker accidents near ports and in rivers. The correct answer is option c.

Considering the various ways in which oil pollution can reach the North American oceans, the greatest amount of oil pollution comes from large oil tanker accidents near ports and in rivers. The oil tanker accidents occur because of the breaking of oil tankers while they are transporting oil to different countries through the ocean water.

The oil pollution results in severe damage to the aquatic life of the oceans. It is the largest cause of water pollution, which is why measures are taken by different environmental organizations to prevent oil pollution from reaching the oceans, leading to severe consequences on a global scale. The other sources of oil pollution are also harmful to the aquatic life, but the impact of large oil tanker accidents near ports and in rivers is greater than other sources.
