Answer 2

Let's analyze each statement:

A. "The present perfect simple is used to talk about an action that has finished but has an effect in the present."

True. The present perfect simple is used to describe an action that happened at an indefinite time in the past and has relevance or connection to the present. The emphasis is on the result or the continuing effect of the action rather than the specific time it occurred.

B. "The present perfect simple is used to talk about an action or state that started in the past and continues to the present."

True. The present perfect simple can be used to express actions or states that began in the past and are still relevant or ongoing in the present. This tense highlights the duration or continuation of the activity.

C. "The past simple is used to talk about experiences that have or haven't happened at an unspecified time in the past."

False. The past simple is generally used to describe completed actions or events that happened at a specific point or during a specific period in the past. It doesn't focus on whether the experience happened or not; instead, it provides information about when the action occurred.

Now let's apply these concepts to the sentences:

1. "The Internet HAS BECOME more and more popular."

True. The present perfect "has become" suggests a change that started in the past (the Internet becoming more popular) and continues to the present.

2. "Ninety per cent of us HAVE SENT or received an email."

True. The present perfect "have sent" indicates an action that started in the past (sending or receiving emails) and is relevant to the present.

3. "Fifteen years ago very few people USED the Internet."

True. The past simple "used" describes a specific action (using the Internet) that occurred in the past.

4. "In the past 15 years the Internet HAS OPENED UP a whole new world to us."

True. The present perfect "has opened up" suggests a process that began in the past (the Internet opening up a new world) and has a connection to the present.

In summary, all the statements are true, and the sentences provided are correctly constructed with the appropriate verb tenses.
