To distinguish between properties of the two major types of supernovae: massive star supernovae and white dwarf supernovae. All

supernovae represent the explosions of stars, but current understanding suggests there are two basic types of supernovae: one that occurs when a massive star reaches the end of its life, and the other that occurs when a white dwarf star explodes because its mass has exceeded the white dwarf limit (also called the Chandrasekhar limit) of 1.4 solar masses.
Match the items below with the correct type of supernova.

1. Star explodes completely, leaving no compact object behind.
2. Can only occur in a galaxy with ongoing star formation.
3. Black hole or neutron star left behind.
4. Can only occur in a binary system.
5. Can occur in a very old star cluster.
6. Spectra always lack strong hydrogen lines.
7. Has a brighter peak luminosity.

Answer: Massive star supernovae

2. Can only occur in a galaxy with ongoing star formation.

3. Black hole or neutron star left behind.

White dwarf supernovae

1. Star explodes completely, leaving no compact object behind.

4. Can only occur in a binary system.

5. Can occur in a very old star cluster.

6. Spectra always lack strong hydrogen lines.

7. Has a brighter peak luminosity.

Explanation:  A supernova is a bright explosion of a star as it dies off. Supernova can occur due to the star losing the heat at its core which eventually makes it collapse. This is the type of supernova formed when massive stars die. They occur in a galaxy with ongoing star formation and a black hole or neutron star left behind.

Supernovae can also be occur when a star orbits another and crashes into another. This is what occurs in a white dwarf . This is part of a binary system,  can occur in a very old star cluster and leaves no compact object behind.

explain why some children in India do not get access to education, even though the Indian government have made education compuls
Effectus [21]

Answer:

Explanation:

Search out Greg Mortenson on the internet. With the help of a ghost writer, he wrote Three Cups of Tea. It has moved a great many people including me. It is the story of a mountain climber who wandered aimlessly in the a poor region of Pakistan (but the same comments apply to India). He collapsed in a village where, had he landed anywhere else, he likely would have been left to die.

Eventually after dealing with all sorts of problems (including the Taliban), he comes to realize that the only way out of poverty the people of this village endured  (and many others like it) was education. From that moment on, he dedicated himself to raising money to build schools in areas like the one that found him. His firm belief was that Education was the only answer.

I think the answer to your question is isolation. Some areas of India are just too isolated and too poor to do anything about education. A whole much better description is in 3 cups of tea and if you are serious about your question, you will find it and read it.
