Explanation:

Note that, stating the converse of a statement in logic simply involves you reverse the initial two statements (hypothesis &conclusion [S&P]).

a. No people who are considerate of others are reckless drivers who pay no attention to traffic regulations.

We could deduce from this statement that the equivalent (reverse) to be:

No S is P ≥ No P is S (where S represents the hypothesis, and P represents the conclusion)

The converse read; No reckless drivers are considerate of others.

b. All graduates of West Point are commissioned officers in the U.S. Army.

We could deduce from this statement that the equivalent (reverse) to be:

All S is P -> Some P is S

The converse read; Some commissioned officers of West Point are graduates

c. Some European cars are overpriced and underpowered automobiles.

We could deduce from this statement that the equivalent (reverse) to be: Some S are P -> Some P is S

The converse read; Some overpriced cars and underpowered automobiles are European cars

d. No reptiles are warm-blooded animals.

We could deduce from this statement that the equivalent (reverse) to be:

No S is P -> No P is S

The converse read; No warm-blooded animals are reptiles.

e. Some professional wrestlers are elderly persons who are incapable of doing an honest day’s work

We could deduce from this statement that the equivalent (reverse) to be: Some S is P -> Some P is S

The converse read; Some elderly persons are professional wrestlers

neonofarm [45]

This film version is extremely different from the play in a number of ways. For example, all of the Porter’s racy lines had to be cut, censorship being super strict in the 1940s. Moreover, the character of Donalbain is removed altogether and many lines were edited or reassigned.Welles had chosen to add a character, the Holy Man, whose purpose, according to the director and star, was to portray the battle between the ‘old’ religion (Paganism) and ‘new’ religion (Christianity).
