Toddlers are watching television more than twice as much as they did two decades ago. A recent research showed that because of this, toddlers today develop their motor skills slower than children their age in the compared period. Therefore, toddlers who spend most of their time in front of the TV have less developed motor skills than those who spend the majority of their time in other occupations.

The argument depends on which of the following assumptions?


(A) Television can be used to enhance many skills of children aged 1-3.

(B) Overall, watching television has a negative effect on young children.

(C) Toddlers should be encouraged to play outdoors more.

(D) Toddlers who watch less television are engaged in activities which develop their motor skills.

(E) Only the physical removal of the television set from homes with young children will enable them to develop their motor skills more quickly.

Key Highlight: Toddlers who spend most of their time in front of the TV have less developed motor skills than those who spend the majority of their time in other occupations.

The assumptions used here is

(A) Television can be used to enhance many skills of children aged 1-3. (No particular age restriction is set on watching TV)

(B) Overall, watching television has a negative effect on young children. (Can be the assumption but it has nothing to do with the main point, the comparison between children of two different time is still unclear here)

(C) Toddlers should be encouraged to play outdoors more. (Its the definite conclusion, but can't be the sole assumption as it still don't consider the main point)

(D) Toddlers who watch less television are engaged in activities which develop their motor skills. (that's exactly what author wants to convey. the comparison is drawn on motor skills of children of two different time period.) (Correct)


(E) Only the physical removal of the television set from homes with young children will enable them to develop their motor skills more quickly. (Its not necessary that removing TV from home will encourage children to play outside)

IMO D

OPtion A - nothing mentioned ( X )

Option B - this can be considered but nothing mentioned about the time ( X )

Option C - this can't be the assumption as nothing mentioned in the conclusion. ( X )

Option D - this hits the conclusion because the whole passage is about toddlers who watch television develop motor skills slower compared to that of earlier period. ( ✔ )

Option E - this looks too out of scope ( X )

OFFICIAL EXPLANATION



Toddlers are watching television more than twice as much as they did two decades ago. A recent research showed that because of this, toddlers today develop their motor skills slower than children their age in the compared period. Therefore, toddlers who spend most of their time in front of the TV have less developed motor skills than those who spend the majority of their time in other occupations.

The argument depends on which of the following assumptions?



(A) Television can be used to enhance many skills of children aged 1-3.

Incorrect.

To solve this Assumption question, first break down the argument. The third sentence includes a conclusion conjunction (therefore) so it's the conclusion, and the first two present findings, so they are the premises:

    Premise A: toddlers today watch more TV than did toddlers 20 years ago
    +
    Premise B: because of that, toddlers today develop motor skills more slowly
    +
    Assumption: ?
    =
    Conclusion: toddlers who watch lots of TV have less motor skill than those who don't

Now ask yourself: what is the missing link? What is the author assuming to be true?

This answer choice contradicts the author's conclusion and therefore cannot be the assumption made by him or her.



(B) Overall, watching television has a negative effect on young children.

Incorrect.

This answer choice goes beyond the scope of the conclusion, expanding the negative effects of TV beyond motor skills. Since the conclusion focuses on motor skills, this cannot be the assumption underlying the argument.



(C) Toddlers should be encouraged to play outdoors more.

Incorrect.

This answer choice is phrased as a conclusion (recommendation); while this may be a valid inference based on the premises, it does not explain how the author got to the existing conclusion.



(D) Toddlers who watch less television are engaged in activities which develop their motor skills.

Even if TV causes a slower development of motor skills, in order to conclude that toddlers who watch TV have less developed motor skill than those who don't, the author had to assume that toddlers who don't watch TV actually do something that does develop motor skills, and not just supplant TV with other body-numbing activities.


(E) Only the physical removal of the television set from homes with young children will enable them to develop their motor skills more quickly.

Incorrect.

To solve this Assumption question, first break down the argument. The third sentence includes a conclusion conjunction (therefore) so it's the conclusion, and the first two present findings, so they are the premises:

    Premise A: toddlers today watch more TV than did toddlers 20 years ago
    +
    Premise B: because of that, toddlers today develop motor skills more slowly
    +
    Assumption: ?
    =
    Conclusion: toddlers who watch lots of TV have less motor skill than those who don't

Now ask yourself: what is the missing link? What is the author assuming to be true?

Incorrect.

This answer choice is phrased as a conclusion (recommendation); while this may be a valid inference based on the premises, it does not explain how the author got to the existing conclusion.
