Raising the humidity of a room protects furniture, draperies, and computers from damage caused by excessively dry air.

Information

causal (doing X protects Y)

raise humidity ⇢ protect furniture, drapes, of the room and computers from damage from dry air

causal (make, helps, alleviates)

raise humidity ⇢ people feel warmer & of the room helps attack viruses & alleviates some rashes

Evaluate

We were basically told four different things that can result from raising the humidity of the room: 1. Some objects are protected from being damaged by air that's too dry 2. People feel warmer 3. It helps the body defend against viruses 4. it can alleviate some skin rashes

Goal

Let's find four supportable answers, based on what we were told.

4.

Each of the following is supported by the information above EXCEPT:

  1. Correct

    Humidity can be bad for

    Why this is right

    We have no support for the idea that humidity can be bad for computers. To the contrary, it sounds like humidity is good. The first sentence says that "more humidity helps to protect computers from air that's too dry". We can infer that "excessive dryness can be bad for computers".

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

  2. A room can be too

    Supported

    This is supported by the first sentence. If a boost in humidity can protect furniture from damage caused by excessively dry air, then we know that excessively dry air can damage furniture.

  3. Dry air can feel cooler

    Supported

    We're told in the second sentence that "raising the humidity can make people feel warmer". We're not changing the temperature of the air, just raising the humidity. We're going from drier air to more humid air, and that change is causing people to feel warmer. So apparently dry air feels less warm (i.e. cooler) than humid air does. (This is why people who live in 110-degree temperatures in Arizona will balk at this number and say, "Oh, it's not too bad. It's a dry heat". And that's why going to Alabama or Florida even when it's 85 degrees can feel sweltering, because those areas are super humid.)

  4. Increased humidity can be beneficial

    Supported

    We're told in the 2nd sentence that "raising humidity can alleviate some skin rashes". Is clearing up a skin rash something that is "beneficial to the skin"? Sure!

    2% picked this

  5. The human immune system can

    Supported

    We're told in the 2nd sentence that "raising humidity can help the body's defenses (i.e. its immune system) against viruses". Being helped = benefiting
