Proxy servers are used in the intranet or extranet (a computer network that allows controlled access from outside the intranet of the organization). Client computers are not connected directly to the Internet in the organization. They are connected to the Internet through proxy servers.

The correct answer is: "call on​."

Let's look at the meanings of the given options:

• blow up- to destroy by an explosion.
• call on- to pay a visit.
• carry on- to continue.
• back out- to choose not to do something agreed upon.
• carry out- perform a task.

According to the context of the given sentence, Mr. Henry visited the subject last Saturday.
So, from the given meanings, we find that call on is the correct choice here.

Correct Sentence is: My uncle lives in a home for the elderly.

The definite article 'the' is used with the name of things that are unique or already mentioned before. Whereas the article 'a' is used with the name of things that are not specific.

The article 'an' is used with the words having the sound of a vowel.

For example:

I met a person on my way to the office. The person turned out to be an old friend.

According to the rules given above, the article 'a' can never be used with a word starting with a vowel. The options (A), (C), and (D) will become invalid as the article 'a' cannot be used with 'elderly'.

Hence the (B) option will be the most appropriate choice in the current scenario.

Correct Sentence is: He wanted to become an artist and live in the Himalayas.

'An' is used when the noun begins with a vowel (a). The noun 'artist' is not a specific one, and 'Himalayas' is a proper noun that is plural.

We generally do not place an article before proper nouns. But when the noun is unique and there is no other noun with the same name, then we place 'the' before it.

There may be multiple Foreign and Primary keys linked to each other. Therefore, The function that an entity plays in a relationship is called that entity’s role.
