Hi!

A in this answer seems wrong because the construction project is sufficient vis-a-vis town economy not necessary.

I diagrammed Answer B as IF CR Produce Benefits to every resident THEN vote for Tax,

Can you explain why E is superior and why B is wrong?

Thanks

Hi djcfrims!

Answer choice (B) states: "The residents of a town should not vote in favor of a local tax to fund a construction project unless that construction project will produce results that benefit all of those residents."

The Unless Equation gives us a two step process for diagramming statements using the term "unless":
1.) Whatever term is modified by "unless" becomes our necessary condition (end of our arrow).
2.) The remaining term gets negated before it becomes our sufficient condition (beginning of our arrow).

So for (B):
1.) "Unless" modifies "construction project will produce results that benefit all of those residents," so that is our necessary condition.
2.) The negation of the remaining term is "The residents of a town should vote in favor of a local tax to fund a construction project."

So the diagram is:

Residents should vote in favor of local tax Construction project will benefit all of those residents

That's a Mistaken Reversal of what we're looking for based on the stimulus.

Answer choice (E), however, gets the relationship in the right direction: "Anyone who would benefit from the results of a construction project should vote in favor of a local tax to fund that project."

"Anyone" is a sufficient indicator so the diagram would be:

Benefit from the results of construction project Vote in favor of local tax to fund construction project

Note that the Unless Equation also applies to the terms "until," "except," and "without." Be on the lookout for those terms and be careful when you are diagramming statements with them. Have that Unless Equation memorized!

Hope this helps!

Best,
Kelsey
