Answers

This question is incomplete. I looked it up online, and this is what I found:

Select the correct answer.

Which sentence describes an achievement of the Roman Empire that survived its fall?

A.  Roman and Greek classics helped promote learning.

B.  Paper was created and used to keep a written history.

C.  The J.ulian calendar was used to keep track of time.

D.  The waterwheel was used to boost agriculture.

Answer:

The sentence which describes an achievement of the Roman Empire that survived its fall is:

C. The J.ulian calendar was used to keep track of time.

Explanation:

The J.ulian calendar is the calendar we use nowadays. It was proposed by Julius Caesar in 46 BC, which is why it is referred to as "J.ulian". This calendar reformed the ancient Roman calendar. It is important to note that the calendar we use today is the result of several changes, some bigger than others. For instance, at a certain point, the calendar consisted of only 10 months. Later, when it already possessed the twelve months used now, some days were added to some of them, eventually adding up to the 365 days we are used to.

Note: The word "J.ulian" is typed this way because Brainly interprets it as a bad word or as a link, which prevents me from posting the answer.

National benchmark test

Looking at the implications of the designated list of recognised subjects being revoked, we see that the requirement actually requires students to attain 50% in any four subjects they wish which has 20 credits in the list.

An advantage this poses is that it will be easier for students to pick subjects that they are confident in and which will be likely relevant to their education.

A disadvantage is that students might end up going for the easiest subjects just with the aim of securing admission into the higher institution.

NBT actually stands for National Benchmark Test.

Write a Informative essay explaining the impact of music on humans.

Answers

Answer:

Explanation:

Music can help people in many ways. Music is known to help people with memory and language problems by helping them remember and learning how to speak again. It can also improve your health and productivity and it serves as a form of expression, as well as a way for teenagers to understand and identify some emotions that they might be feeling. Listening to music is also good for people who are under a lot of stress, so they can relax and sleep better. Because taking music lessons can also improve many skills, it’s recommendable to get involved with it to help yourself in school or work. For patients with mental illnesses, like Alzheimer's and dementia, taking music therapy can be really helpful mentally, physically, and emotionally. Musicians have a better memory than people who don’t know how to play an instrument. This is because their training gives them a high working-memory brain. Having this is good because it enhances thinking and concentration, and you develop better listening abilities. Music training can improve verbal memory and attention.
