Answer:
As the main sequence star glows, hydrogen in its core is converted into helium by nuclear fusion. When the hydrogen supply in the core begins to run out, and the star is no longer generating heat by nuclear fusion, the core becomes unstable and contracts. The outer shell of the star, which is still mostly hydrogen, starts to expand. As it expands, it cools and glows red. The star has now reached the red giant phase. It is red because it is cooler than it was in the main sequence star stage and it is a giant because the outer shell has expanded outward. In the core of the red giant, helium fuses into carbon. All stars evolve the same way up to the red giant phase. The amount of mass a star has determines which of the following life cycle paths it will take from there.

The life cycle of a low mass star (left oval) and a high mass star (right oval).
the different evolutionary paths low-mass stars (like our Sun) and high-mass stars take after the red giant phase. For low-mass stars (left hand side), after the helium has fused into carbon, the core collapses again. As the core collapses, the outer layers of the star are expelled. A planetary nebula is formed by the outer layers. The core remains as a white dwarf and eventually cools to become a black dwarf.

Options:
a. There are over two million foreign-born workers in the United Kingdom.
b. Migrant workers are a strain on the UK's economy and support few other jobs or industries.
c. Migrant workers contribute taxes and pay into the national insurance.
d. Migrant workers contribute $87 billion to the UK's economy and over $195 million to the UK's GDP
Answer:
a. There are over two million foreign-born workers in the United Kingdom
According to migrationobservatory, about 9.3million foreign-born workers are in the United Kingdom. This makes up about 14% of the total population of U.K. The size has been on the increase through the years. The two million given in the option is wrong and not a statement of fact.
