Child psychologist: Psychologists have found that most children under the age of six are egocentric and selfish in their attitudes toward animals. Ordinarily, it is only between the ages of six and nine that children begin to understand that animals are independent creatures with their own feelings and needs. Hence, most children should not have pets until they are at least six years old.

Summary
The author concludes that most children shouldn’t have pets until they’re at least 6 years old. Why?
Because most children under 6 are egocentric and selfish in their attitudes toward animals.
In addition, most children under 6 don’t understand that animals are independent creatures with their own feelings and needs.

Missing Connection
The conclusion brings up a new concept — shouldn’t have pets. The premises don’t say anything about who shouldn’t have pets. So, at a minimum, the correct answer needs to tell us about people who shouldn’t have pets.
To go further, we can anticipate a more specific connection between the premises and the conclusion. Any answer that connects a feature we know about most children under 6 to “should not have pets” can be correct:
If one is egocentric and selfish in attitudes toward animals, then one shouldn’t have a pet.
or
If one doesn’t understand that animals are independent creatures with their own feelings and needs, then one shouldn’t have a pet.

A
Most children who are egocentric and selfish in their attitudes towards animals rely on others to take care of a pet.
(A) doesn’t establish anything about who shouldn’t have a pet. Since neither this answer nor the premises establish who shouldn’t have a pet, it can’t make the argument valid.
B
Children who are old enough to understand that animals are independent creatures with their own feelings and needs should be allowed to have pets.
(B) allows us to conclude that certain children SHOULD be allowed to have pets. But we’re trying to prove that certain children should NOT be allowed to have pets. (B) is the sufficiency/necessity confused version of what we want.
C
Most children who are egocentric and selfish in their attitudes towards animals do not have pets.
(C) doesn’t establish anything about who shouldn’t have a pet. Since neither this answer nor the premises establish who shouldn’t have a pet, it can’t make the argument valid.
D
Most children are egocentric and selfish in their attitudes towards their pets and do not understand that their pets are independent creatures with their own feelings and needs.
(D) doesn’t establish anything about who shouldn’t have a pet. Since neither this answer nor the premises establish who shouldn’t have a pet, it can’t make the argument valid.
E
The only children who should have pets are those who understand that their pets are independent creatures with their own feelings and needs.
(E) establishes that in order for a child to be one that should have a pet, the child must understand the pet is an independent creature. Since we know from the premises that most children under 6 don’t understand this, (E) allows us to conclude that most children under 6 shouldn’t have a pet.

Because of the ubiquity of television in modern households, few children today spend their free time reading stories, which lack the visual appeal of flashy television programs. Thus, few children today will develop a lifelong interest in literature.

Summary
The author concludes that most children today will NOT develop a lifelong interest in literature. (”Few X are Y” = “Most X are NOT Y.”)
Why?
Because most children today do NOT spend their free time reading stories.

Missing Connection
We’re trying to prove that most children won’t develop a lifelong interest in literature. But the premise doesn’t tell us anything about what leads to “won’t develop a lifelong interest in literature.” So, at a minimum, the correct answer must establish what’s necessary in order for developing a lifelong interest in literature.
To go further, we can anticipate a more specific relationship that will get us from the premise to the conclusion:
If one does not spend their free time reading stories, one will not develop a lifelong interest in literature. (Or in other words, in order to develop a lifelong interest in literature, one must spend their free time reading stories.)

A
No children who spend their free time reading stories fail to develop a lifelong interest in literature.
(A) asserts that if a child does spend free time reading stories, they will develop a lifelong interest in literature. But we want to know that if a child does NOT spend free time reading stories, they will NOT develop the interest. (A) is the sufficiency/necessity confused version of what we want.
B
Only those people who currently spend their free time reading stories will develop a lifelong interest in literature.
(B) establishes that in order to develop a lifelong interest in literature, one must currently spend their free time reading stories. Since we know that most children don’t currently spend their free time reading stories, (B) allows us to conclude that those children won’t develop a lifelong interest in literature.
C
No children who grow up in a household that lacks a television fail to spend their free time reading stories.
(C) doesn’t establish what’s required in order to develop a lifelong interest in reading literature. Since neither this answer nor the premise tells us what’s required to develop a lifelong interest in reading literature, it cannot make the argument valid.
D
Few people who watch a great deal of television develop a lifelong interest in literature.
(D) establishes that most people who watch a “great deal” of TV will not develop a lifelong interest in literature. But we don’t know whether most children spend a “great deal” of time watching TV. In addition, (D) leaves open the possibility that children could be among the minority of people who could watch a lot of TV and still develop a lifelong interest in great literature.
E
Few children who spend their free time reading stories watch television.
(E) doesn’t establish what’s required in order to develop a lifelong interest in reading literature. Since neither this answer nor the premise tells us what’s required to develop a lifelong interest in reading literature, it cannot make the argument valid.
