Twenty percent of all energy consumed in the United States is consumed by home appliances. If appliances that are twice as energy-efficient as those currently available are produced, this figure will eventually be reduced to about ten percent.

The argument above requires which of the following assumptions?

(A) Home-appliance usage would not increase along with the energy efficiency of the appliances.

(B) It would not be expensive to produce home appliances that are energy-efficient.

(C) Home-appliance manufacturers now have the technology to produce appliances that are twice as energy-efficient as those currently available.

(D) The cost of energy to the consumer world rise with increases in the energy efficiency of home appliances.

(E) The percentage of energy consumed by home appliances will increase if existing appliances are not replaced by more energy-efficient models.

Twenty percent of all energy consumed in the United States is
consumed by home appliances. If appliances that are twice as energy-
efficient as those currently available are produced, this figure will
eventually be reduced to about ten percent.

(A) Home-appliance usage would not increase along with the energy
efficiency of the appliances.
(B) It would not be expensive to produce home appliances that are
energyefficient.
(C) Home-appliance manufacturers now have the technology to produce
appliances that are twice as energy-efficient as those currently
available.
(D) The cost of energy to the consumer world rise with increases in
the energy efficiency of home appliances.
(E) The percentage of energy consumed by home appliances will
increase if existing appliances are not replaced by more energy-
efficient models.

Home appliances consume 20% of energy in US.
If twice energy efficient appliances are produced, this figure will come down to 10%.

We can conclude this only if the consumption remains the same.
If the consumption increases after the introduction of energy efficient appliance, then the percentage will not decreases.

Correct Option: A

This is an assumption question so the conclusion has to be strengthened. What the argument is saying is that change appliance make them efficient then the energy will be saved..

If i prethink i will have answers like- people will use the new items , they have money to replace these

all answers relating to other things are irrelevant.

crux has to be these need to be used.

A says that these are using but the usage behavior is not changing.

hmmm- "BA- BAAM" ourr answer- same usage behavior and the use of these.

the argument for the stimulus is that the consumption percentage will reduce from 20% to 10% when twice as efficient home appliances are used.

B) irrelevant as it does not talk about energy consumption
C) irrelevant even though it talks about manufacturing the appliances within the argument but it fails to support the reduction in energy consumption
D) irrelevant cost of energy has nothing to do with energy consumption %
E) irrelevant does not support conclusion, argument talks about appliances that are twice as efficient, this one talks about existing home appliances

A) is correct because, if usage remains the same and home appliances become twice as efficient then consumption reduces by half

This is from my understand.

The argument above requires which of the following assumptions?

(A) Home-appliance usage would not increase along with the energy efficiency of the appliances. -- negate: usage increases so plan backfires

(B) It would not be expensive to produce home appliances that are energy-efficient. -- expensive - frameshift

(C) Home-appliance manufacturers now have the technology to produce appliances that are twice as energy-efficient as those currently available. -- we dont need this because its an extention of the logical conditioning - If appliances that are twice as energy-efficient as those currently available are produced -

(D) The cost of energy to the consumer world rise with increases in the energy efficiency of home appliances. -- sounds like a hypothesis

(E) The percentage of energy consumed by home appliances will increase if existing appliances are not replaced by more energy-efficient models. -- negate: the % will not increase: which means either stay the same or go down -.. bidirectional.
