If you were writing a research paper about wind turbines, which sentence from the passage would be irrelevant to your research? a) the most common type of turbine has blades like airplane propellers. b) over 5,000 years ago, ancient egyptians used wind to sail ships on the nile river. c) people often build the turbines close together in a wind-power plant called a wind farm. d) instead of using that energy for simple tasks, though, turbines turn the energy into electricity. need asap

I believe the answer to your question is B) Over 5,000 years ago, ancient Egyptians used wind to sail ships on the Nile River.

this sentence from the passage would be irrelevant because it does not contain usable information on wind turbines as well as the fact that it is a time in history therefore it is irrelevant because you need information that is relatively up-to-date.

The correct answer is B Over 5,000 years ago, ancient Egyptians used wind to sail ships on the Nile River.

postards have pictures on them, these pictures are things that may never be seen again. the pictures are a part of our history that shows things. because of this many collectors would pay a lot of money for them.

i read on google they "offer a glimpse into the past"

hope this : )

the support that the author, uses in the article facing our fears is a): a definition of the part of the brain called the amygdala.

he takes neuroscientist joseph ledoux's words by telling that by falling to distinguish between evolutionary old systems located in the amygdala and newer systems, centered in the prefrontal cortex, doctors have conflated non conscious threat circuits in the brain with circuits that underlie the conscious experience of fear. that, the author says, "leads ledoux to the jarring conclusion that the amygdala, a decades-old centerpiece of the brain's fear circuit, does not underlie the conscious feeling of fear".

despite this, the author points out in the article that that is a controversial notion and that evidence, in animal and humans, supports the idea that core emotions can exist outside of conscious awareness.
