Identify the Four Premises that make up this argument: (Answers must be verbatim, including punctuation)
You think that if the victims of the mass shooting had been armed that would’ve made things better? Are you nuts? The shooting took place in a bar; not even the NRA thinks it’s a good idea to allow people to carry guns in a drinking establishment. And don’t be fooled by the fantasy that “good guys with guns” would prevent mass murder. More likely, the situation would’ve been even bloodier, with panicked people shooting randomly all over the place.

Write down the tacit conclusion that follows most immediately from the following premises:

The death penalty is immoral. Numerous studies have shown that there is racial bias in its application. The rise of DNA testing has exonerated scores of inmates on death row; who knows how many innocent people have been killed in the past? The death penalty is also impractical. Revenge is counterproductive: “An eye for an eye leaves the whole world blind,” as Gandhi said. Moreover, the costs of litigating death penalty cases, with their endless appeals, are enormous. The correct decision for policymakers is clear.

This is how natural selection works: those species with traits that promote reproduction tend to have an advantage over competitors and survive; those without such traits tend to die off. The way that humans reproduce is by having sex. Since the human species has survived, it must have traits that encourage reproduction—that encourage having sex. This is why sex feels good. Sex feels good because if it didn’t, the species would not have survived. [Context: excerpt from Evolutionary Biology for Dummies]

Because different wavelengths of light travel at different velocities when they pass through water droplets, they are refracted at different angles. Because these different wavelengths correspond to different colors, we see the colors separated. Therefore, if the conditions are right, rainbows appear when the sun shines through the rain.
