“The most likely source was heat from a fire in the coal bunker adjacent to the 6-inch reserve magazine.”

The second one

Explanation:

The others don't make sense

Explanation:

Education

Illiteracy is the biggest reason behind poverty in India. Illiterate people living in rural areas, villages and small towns are the most vulnerable to unemployment. More than 51% of the rural population earns from casual labour. A huge chunk of population works on farms and makes a living. Education is necessary to enhance their farm productivity and overall income. Educated people can also find new jobs, which can help them overcome poverty. Girl child education is also important for the society. Educated girls can grow into skilled workers and get well-paying jobs. Working women can earn and support families, thus giving their kids a better standard of living.

Investment on infrastructure

India’s poverty crisis also arises from the dearth of basic infrastructure like schools, hospitals, toilets, electricity and non-polluting heating options. The government must look to invest in the infrastructure of the country, which can go a long way and help build an environment suitable for enterprise development and income generation.

Skill development

Today most of the industries seek skilled labourers and workers. The government must introduce new programs for people to learn basic skills that can help them find jobs. Development of vocational and technical skills is also very important to eradicate poverty from the country.
