Columnist: The advent of television helps to explain why the growth in homicide rates in urban areas began significantly earlier than the growth in homicide rates in rural areas.

Conclusion

The invention of TV helps explain why homicide rates in urban areas grew before that in rural areas.

Evidence

TV sets became popular in urban homes about five years before they did in rural homes. And homicide rates started increasing in urban areas about four years earlier than in rural areas.

Evaluate

The author is looking at a Curious Comparison (why did homicide rates go up in urban areas four years before they went up in rural areas?) and then the conclusion is making a Causal claim (the advent of TV helps to explain the growth of homicide rates).

We evaluate this type of argument two ways: - Alternate Explanations for the curious fact? - plausibility of the Author's Explanation?

Why else might urban homicide rates have spiked four years earlier than rural homicide rates?

Maybe urban areas got more guns first. Maybe they had economic anxieties first. Maybe they had problems with drug-related violence first.

How plausible is the author's story?

I don't know, what does TV have to do with committing homicide? Were people seeing violence glorified on TV? Were they jealous of their neighbors who could afford a TV before they could?

Also, we were told the date of when homicide rates went up (1958), but not the date of the advent of TV. If that latter date is really far removed from 1958, then it's harder to believe that TV and homicide rates are connected.

Goal

Since this is Strengthen, we'll need an answer choice to either - rule out an alternate explanation for why homicide rates went up in urban areas a few years before doing so in rural areas. or - add plausibility to the Author's explanation that the advent of TV is responsible.

Which one of the following, if true, most supports the columnist's argument?

  1. In places where the number

    Unclear Impact

    We might keep this on a first pass. It seems to provide data points that feel like the classic plausibility-Strengthener: where cause is absent, effect is absent. This answer has the feel of "Where there were fewer violent TV shows, there was less homicide". But, the author hasn't said anything about "violent programs" being the reason that TV led to more homicide, though, so we'd be speculating a little to think that our author was assuming that's how TV led to homicide. Also, because this language is expressed in terms of absolute, not relative, language, it's not clear what impact it would have. When we say that urban homicide rates "grew" earlier than rural homicide rates did, we're not saying they started from around the same rate and grew to the same rate. We're just saying, whatever they were at in 1958, the urban rate increased before the rural rate increased. A rural rate might have such a low average homicide rate that even once it increases you would still call it a "low" homicide rate. It's higher than before, but it's still not high. So this answer doesn't really clarify whether in these areas with low numbers of violent TV shows the homicide rate was stable or increasing.

  2. Correct

    The portrayal of violence on

    Why this is right

    This helps the plausibility of the author's explanation, that the advent of TV helps to explain the growth in homicide rates. We were wondering to ourselves, "What does TV even have to do with homicide rates?" This answer tells us, "The portrayal of violence on TV causes violence in society". So it provides some support to the argument. The author hadn't yet established any sense of how TV could lead to homicide, but this answer choice helps fill in that blank.

    Skill tested: Strengthen · how this choice captures the argument's function is the move to repeat next time.

  3. There were no violent television

    Weakens, if anything

    For each of these first three answers, LSAC seems to be thinking that we should just assume that the author's concern is the effect of violent TV on the audience. That, of course, is the most common sense hypothesis of how TV could lead to more killing (but not the only one). At any rate, if we think our author is suspecting that the advent of TV led to more homicides because violent TV corrupts some of the audience into being more aggressive and violent, then this answer choice would totally weaken that storyline. If early TV was just soap operas and puppet shows, then whether you had TV or didn't wouldn't seem to have much effect on your violent tendencies.

  4. The earlier one is exposed

    Unclear Impact

    There are two issues with trying to interpret this answer: 1. when we say "the earlier one is exposed to TV", I interpret that to probably mean "the earlier in life", i.e. "the younger you are when you're exposed to violent TV". This argument isn't about urban kids seeing violent TV at a younger age than rural kids did. It's just about "when TV arrived in your city". It would be weird to interpret "the earlier you're exposed to TV" as meaning "the earlier in the 20th century that TV became prevalent in your area". 2. "... the more profound the effect" is very vague. What is the effect? We have never established in this argument that TV has any effect on anyone, so we don't know what sort of 'effect' this is alluding to. Seeing violence on TV might make you more averse to violence, in which case this answer would weaken the argument.

  5. Increasing one’s amount of leisure

    Unclear Impact

    In order for us to make this relevant, we would have to assume that when the advent of TV came to your area, it increased your amount of leisure time. But that doesn't make a lot of common sense. You had what leisure time you had, either way. TV is an option to fill leisure time, but it doesn't inherently create or increase your amount of leisure time.
