Question

dogs are the worlds most popular pet. with over 400 dog breeds in existence, there are lots of great dogs to choose from. but how do you choose? start by looking at the characteristics of different dog breeds: think about the size of a dog, its personality, and how it looks.

chihuahuas are known as a \toy breed\ because they are very small. chihuahuas weigh about 5 pounds and grow up to 6 inches tall. in contrast, saint bernards are huge. this friendly giant can weigh up to 200 pounds and grow about 30 inches tall! a chihuahua would be happy living in a small apartment because it needs little space.

dogs personalities, similar to humans. both chihuahuas and saint bernards, are loyal and friendly. they like to please the humans they live with. saint bernards are gentle and patient with children, like a babysitter. chihuahuas are also good with children. even though the chihuahua is small, it can act like a big dog by barking a lot. chihuahuas are suspicious of strangers. saint bernards dont bark very much and are friendly with everyone.

chihuahuas have short hair that doesnt get very dirty, but saint bernards have thick, curly coats that pick up dirt. saint bernards need to have their coats brushed every week to keep them clean. drooling is a characteristic of some dogs, including the saint bernard, but chihuahuas drool very little.

1 which fact from paragraph 2 explains why saint bernards would be unhappy in a small apartment?
a. they are known as a toy breed.
b. they are very friendly dogs.
c. they grow to be about eight inches tall.
d. they can weigh up to 200 pounds.

Explanation:

Paragraph 2 states Saint Bernards are huge, weighing up to 200 pounds and needing more space. A small apartment lacks the space such a large dog requires, so their large size (evidenced by their maximum weight) explains their unhappiness there. The other options are incorrect: A and C describe Chihuahuas, and B (friendliness) does not relate to space needs.

Answer:

D. They can weigh up to 200 pounds.
