During a professional baseball game, a long fly ball is hit down the first base line toward the foul ball pole. If it goes to the right of the pole it will be a foul ball, and if it goes to the left it will be a home run. The umpire making this call will have the most difficulty making the judgment because . a. it can be very difficult to distinguish one item from another when it there is overlap between the two. b. the ball will probably disappear from view whether it goes in front of or behind the foul pole. c. the human visual perceptual system is simply inefficient at making judgments in cases where the visual stimuli are more than a few feet away. d. the umpire will be looking right at the foul pole instead of viewing it from an angle.

A -  it can be very difficult to distinguish one item from another when it there is overlap between the two

Explanation:

Baseball is a bat-and-ball game played between two opposing teams who take turns batting and fielding. The game proceeds when a player on the fielding team called the pitcher throws a ball which a player on the batting team tries to hit with a bat.

The objective of the offensive team is to hit the ball into the field of play allowing its players to run the bases and having them advance counter-clockwise around four bases to score what are called "runs" while The objective of the defensive team is to prevent batters from becoming runners and to prevent runners' advance around the bases.

There are three basic tools of baseball: the ball, the bat, and the glove

1. The baseball is about the size of an adult's fist, its around 9 inches in circumference and it has a rubber center wound in yarn and covered in white cowhide with red stitching.

2. The bat is a hitting tool, it is traditionally made of a single, solid piece of wood. It is a hard round stick about 2.5 inches in diameter at the hitting end tapering to a narrower handle and culminating in a knob. Bats used by adults are typically around 34 inches  long, and not longer than 42 inches.

3. The glove is a fielding tool made of padded leather with webbing between the fingers. As an aid in catching and holding onto the ball, it takes various shapes to meet the specific needs of different fielding positions.
