Answer:
Correct Answer:
(C) the pipe passed through a diamond-stability field and thus may contain diamonds
Explanation:
The passage from which the question was gotten is attached below:
<u>Diamonds are almost impossible to detect directly</u>
<u></u>
Diamonds are almost impossible to detect directly because they are so rare: very rich kimberlite Line pipes, the routes through which diamonds rise, may contain only three carats of diamonds per ton of kimberlite. Kimberlite begins as magma in Earth's mantle (the layer between the crust and the core).
As the magma smashes through layers of rock, it rips out debris, creating a mix of liquid and solid material. Some of the solid material it brings up may come from a so-called diamond-stability field, where conditions of pressure and temperature are conducive to the formation of diamonds.
If diamonds are to survive, though, they must shoot toward Earth's surface quickly. Otherwise, they revert to graphite or burn. Explorers seeking diamonds look for specks of indicator minerals.

Answer:
1066 MHz
Explanation:
The maximum bus speed of the memory that the motherboard can support is 1600 MHz. This means that if a memory of higher speed is installed then the memory will run at 1600 MHz and no higher.
Here, a memory with DDR3 1066 MHz for one module and DDR3 1333 MHz is installed. The computer is set up in a way that will always select the lower speed.
Hence, the system will function on 1066 MHz.
