Answer:
Formation of Earth. Earth came together (accreted) from the cloud of dust and gas known as the solar nebula nearly 4.6 billion years ago, the same time the Sun and the rest of the solar system formed. Gravity caused small bodies of rock and metal orbiting the proto-Sun to smash together to create larger bodies.
Answer:
Distraction as a way of survival
Explanation:
The narrator speaks about how difficult is to keep on living watching all the survivors around her. Because she's seen death, but what strikes her completely is the living, so she says her "one saving grace is distraction", so she focuses on colors, and other details so as not to think about the destruction that suffocates her.
The correct answer is A. It is difficult to understand the part of "seven years' transportation to America". It seems to me that you should use a passive structure so as to place the kind of sentences that English courts were allowed to give first, and after mention that the first Penal Transportation Act was the one which introduced this change. The other answers do not apply to this sentence, there are no puntuation and spelling mistakes, and there are no unnecessary words.
