Read the following passage and then respond to the directions below. Slow down! Light rail may be the best thing for Phoenix or the worst. The point is, we don't know. Let's take our time in making this multibillion dollar decision. After all, which would you rather be responsible for, revolutionizing our commute system or funding a mobile homeless shelter. Join me in giving city planners more time to analyze whether phoenix is the place for light rail. Vote "no." Explain how the argument illustrates the either-or fallacy and why that fallacy makes the argument weak.

The argument illustrates the either-or fallacy because it only presents two alternatives out of which one should be taken. It  is a fallacy and weakens this argument because one may prefer not to choose from these available alternatives or even prefer to choose both.

Moreover, it is believed that the conjuction of two alternatives is more likely than either of the two alternatives. Believing that doing either a light rail or funding a mobile homeless system are the only things that can make phoenix better is a fallacy.

i think the life is invaluable.

you can also say immeasurable.
