IV.The following passage contains errors. Identify and correct them. 11 these mountain - like formations contain a treasure trove of minerals and 12 metals. The asteroid 16 Psyche has enough iron-nickel ore to sustain the 13 Earth for several million years. Even a comparatively small asteroid could 14 contain more than 2000 million metric tons of serviceable mineral-metal 15 reserves. In additions, some asteroids have a high ice content which 16 means that they could be an economically viable source of freshwater. 17 Large-scale mining of asteroids is possibly the key to solve many of our 18 escalating environmental problems. Any mining venture contains an 19 element of risk, however. Asteroids have traditionally been considered 20 dead perils lurking out in the dark depths of space, bided their time before 21 smashing headlong into our insignificant planet. In order to transplant 22 mining operations from the Earth to the stars, we need to find solutions to 23 extensive safety and logistical problems.

IV. The following paragraph has an error. Identify and correct them.
This mountain-like formation contains a treasure of minerals and metals. Asteroid 16 Psyche has enough iron-nickel ore to maintain. Earth for several million years. Even a relatively small asteroid can contain more than 2000 million tons of mineral metal that can serve its reserves. In addition, some asteroids are high in ice, which means they can be an economical source of fresh water. Exploiting large asteroids may be the key to solving many of our escalating environmental problems. Any mining venture contains a risk factor, however. Asteroids have been traditionally considered for the deadly danger lurking in deep space, farewell their time before banging their heads on our trivial planet. In order to pair the extractive activities from the Earth to the stars, we need to find solutions to safety issues and extended logistics.

This mountain looks like formation contains a treasure of minerals and metals. The Asteroid 16 Psyche has enough iron-nickel ore to maintain The Earth for several million years. Even thought, a relatively small asteroid can contain more than 2000 million tons of mineral metal that can serve its reserves. In addition, some asteroids are high in ice, which means they can be an economical source of fresh water. Exploiting large asteroids may be the key to solving many of our escalating environmental problems. However, mining venture contains a risk factor and asteroids have been traditionally considered for the deadly danger lurking in deep space, farewell their time before banging their heads on our trivial planet. In order to pair the extractive activities from the Earth to the stars, we need to find solutions to safety issues and extended logistic problems.
