Choosing the Best Sentence Starter

The question asks us to find the best sentence starter to combine two simple sentences: "It was a public holiday. All shops were closed." We need to identify the relationship between these two sentences. Being a public holiday is the reason or cause for the shops being closed. Therefore, we need a connector that expresses cause or reason.

Analyzing the Options

Let's look at the given options and see how they would connect the two sentences:

1. While

   Using "While" suggests a contrast or something happening at the same time. "While it was a public holiday, all shops were closed" doesn't logically fit the cause-and-effect relationship. It might imply contrast ("While it was a public holiday, surprisingly...") or simultaneity, neither of which is the intended meaning.

2. As it was a

   "As" can be used to mean "because" or "since," indicating the reason for something. Using "As it was a public holiday, all shops were closed" correctly shows that the public holiday was the reason the shops were closed. This fits the cause-and-effect relationship perfectly.

3. Just as it was a

   "Just as" is typically used to show that two events happen at the same moment or that one situation is very similar to another. "Just as it was a public holiday, all shops were closed" implies the closing happened at the exact moment it became a public holiday or draws a comparison, neither of which captures the reason. It's not suitable for expressing cause and effect.

4. Even though

   "Even though" is used to introduce a concession or contrast. It means "despite the fact that." "Even though it was a public holiday, all shops were closed" would imply that shops are usually open on public holidays, which is the opposite of the intended meaning (shops were closed because it was a public holiday).

Identifying the Correct Connector

Based on the analysis, the sentence starter that correctly expresses the cause-and-effect relationship between the two sentences is "As it was a". It clearly indicates that the public holiday was the reason for the shops being closed.

The combined sentence would be:

As it was a public holiday, all shops were closed.

Conclusion

The best sentence starter among the given options to combine the sentences "It was a public holiday. All shops were closed." is "As it was a" because it correctly establishes the cause (public holiday) and effect (shops closed) relationship.
