"Unless" We Get the Band Back Together

Test 17 - Section 3 - Question 11

Logical Reasoning

Difficulty: 4


Demon user Spencer W asks,

"How is A incorrect? If the city can't build water and sewer systems for new apartments, doesn't that disqualify the idea of apartments being built by developers entirely?"

Ut-oh. It seems as if Spencer doesn't understand how "unless" works, and is therefore confusing sufficient for necessary. But since he asked a good question—thanks Spencer!—he'll soon sort it out.

"Unless" means "if not." So the first sentence means "if the residents don't band together, here's what will happen." Another way of thinking about "unless" is that it's like an escape hatch in a submarine whose hull has been breached and is rapidly filling with water. "Unless we can reach that escape hatch, we're dead meat." This means that if we don't reach the escape hatch we're definitely dead. But it doesn't mean that if we DO reach the hatch we will definitely live. (There could be a giant squid right outside the hatch, ready to give us all the sweet embrace of death. Or we could just bonk our heads and drown like losers.)

A) Returning to the "unless" statement about the residents, we know that "unless" they band together, the proposal will be approved and the city will be able to build water and sewer, thus paving the way for the apartments. But even if the residents do band together, the proposal could be approved anyway. And furthermore, even if the proposal isn't approved, the city might be able to build the water and sewer in some other way. We just don't know.

B) Yep. This is simple and straightforward. The apartments will certainly require new roads. The roads will require a tax increase. So the apartments will require a tax increase. This is the answer because it is 100% proven by the facts.

C) Again, the apartments might be built even without the rezoning approval. And even if the apartments don't come in, maybe a coal-fired power plant, a tannery, a Wal-Mart, and a NASCAR speedway could come in and ruin the rural atmosphere in a million other ways. This is out.

D) Taxes can go up in a million ways as well. Maybe the mayor of Glen Hills decides to build himself an Iron Throne and declare himself king of all he surveys, immediately declaring a 95% tax on all earnings within city limits. You never know.

E) These answers just don't stop confusing sufficient and necessary, do they? The schools could become overcrowded because the kids suddenly start cloning themselves, like Tribbles or Mogwai. Tesla Gigafactories could become self-aware and start self-replicating, covering every square inch of Earth with shiny new Model 3s, while their robotic colonizing forces load onto SpaceX rockets and blast themselves into the solar system—there could be a traffic jam not only in Glen Hills, but also on Mars.

I'll stop. The answer is B because it's clearly, obviously proven by the given facts. All the other answers could be false.
