Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the questions from 34 to 38.

Most Americans say they know at least some of their neighbors, but only about three-in-ten say they know all or most of them. Rural residents are more likely than those in urban or suburban areas to say they know all or most of their neighbors, but they don’t necessarily interact with their neighbors more than their counterparts in other community types.

Overall, Americans tend to be trusting of their neighbors, but this is particularly the case in suburban and rural areas. About six-in-ten in these types of community say they have a neighbor they would trust with a key to their home, compared with about half in urban areas.

The longer people have lived in their community, the more likely they are to have a neighbor they would trust with a key to their home. But even among those who report that they have lived in their community for less than one year, 34% say they would be comfortable with a neighbor having their keys. Meanwhile, 64% of those who have lived in their community for six or more years and 47% of those who have done so for one to five years say the same. Those who own their home are more likely than renters to say they would be comfortable with a neighbor having a set of keys to their home (67% vs. 45%).

When asked to describe their neighbors, people in rural areas are far more likely than those in cities and suburbs to say all or most of their neighbors share their race or ethnicity. Suburbanites are somewhat more likely than their urban and rural counterparts to say their neighbors are the same social class as they are, while relatively few across community types say all or most of their neighbors share their political views.

Which of the following could be the main topic of the passage?

Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the questions from 39 to 45.

While the debate regarding how much screen time is appropriate for children rages on among educators, psychologists, and parents, it’s another emerging technology in the form of artificial intelligence and machine learning that is beginning to alter education tools and institutions and changing what the future might look like in education. It is expected that artificial intelligence in U.S. education will grow by 47.5% from 2017-2021 according to the Artificial Intelligence Market in the US Education Sector report. Even though most experts believe the critical presence of teachers is irreplaceable, there will be many changes to a teacher’s job and to educational best practices.

AI has already been applied to education primarily in some tools that help develop skills and testing systems. As AI educational solutions continue to mature, the hope is that AI can help fill needs gaps in learning and teaching and allow schools and teachers to do more than ever before. AI can drive efficiency, personalization and streamline admin tasks to allow teachers the time and freedom to provide understanding and adaptability—uniquely human capabilities where machines would struggle. By leveraging the best attributes of machines and teachers, the vision for AI in education is one where they work together for the best outcome for students. Since the students of today will need to work in a future where AI is the reality, it’s important that our educational institutions expose students to and use the technology.

Artificial intelligence tools can help make global classrooms available to all including those who speak different languages or who might have visual or hearing impairments. Presentation Translator is a free plug-in for PowerPoint that creates subtitles in real time for what the teacher is saying. This also opens up possibilities for students who might not be able to attend school due to illness or who require learning at a different level or on a particular subject that isn’t available in their own school. AI can help break down silos between schools and between traditional grade levels.
