After reading the sentences and the answer choices, we can choose the following as the best:
1. The word or phrase that can be used to emphasize an important point is: "especially".
2. The phrase that could be added to create cohesion is: "One reason is that."
3. The phrase that goes in the blank is: "For example."
Now, let's break down each of the answers above:
1. Among the options, the only one that can be used for emphasis is "especially". When we emphasize something, we show how important or special it is. Thus, it makes sense to use "especially" to do it.
2. The first sentence states that a beagle is the best pet for a family. The second sentence gives a reason why the first sentence is true. With that in mind, the best phrase is "One reason is that."
3. The sentence that has a blank to be filled is providing an example to support the idea that spring is a good time to start a new routine. With that in mind, the best phrase is "For example."
