This question is missing the excerpt. I've found it online. It is the following:
James Jay's invisible ink did not become visible by heating. As he described it, his ink "would elude the generally known means of detection, and yet could be rendered visible by a suitable counterpart." Jay's invisible ink consisted of two chemicals. An agent used one chemical to write an invisible message. To read the message, the reader had to brush a second chemical on the paper; that chemical made the message visible. The two-bottle system, supplied by Jay, gave Washington the secure form of writing that he wanted.
Answer:
The statement which best expresses the central idea of the excerpt is:
B. James Jay's invisible ink system allowed Washington to write secret messages.
Explanation:
Options A and C have information that we can assume after reading the passage, but that is not explicit in it. Therefore, they cannot refer to the central idea. We can eliminate those options.
<u>Option D mentions the two chemicals required for writing and reading the messages. Even though that piece of information is discussed in the excerpt, it serves more as an explanation of the central idea. In fact, the central idea itself is that Washington was able to write secret messages because of James Jay's invisible ink. That is what the passage is ultimately about. The author is merely explaining how that ink works when he mentions the chemicals. Thus, we can eliminate letter D and choose letter B as the correct option.</u>
Answer:
Making mistakes are part of the human nature. “Anyone who has never made a mistake has never tried anything new” says Albert Einstein. Just like what Albert Einstein said, mistakes are essential for life. I can assure you that everyone makes mistakes.
Most mistakes are unintentional, but so long as you can learn from your mistakes, this mistake becomes an asset of your life learning experience. Occasionally, mistakes are careless mistakes. Careless mistakes are mistakes that would never have existed if you had tried harder. Those mistakes are a big monster with everyone. One day, I had a big test. This test was about 70% of our grade. I had the topic memorized and I knew I was about to ace it! I was done the test in like 10 minutes! We had 30 minutes to do it, but I was done a third of the limited time! My teacher had told the class if we had finished early, we could check our work or we could play some video games on our computer. I picked the more enjoyable option. After a few weeks, we got our test back. My score was a 14 out of 30! When I had checked my mistakes, all of them were so obvious! Luckily, these careless mistakes didn’t affect my grade that much since we took a redo. When I redid my horrible test, I already had learned from my previous mistakes.
You can harm yourself with these immense threats. There are times that mistakes are not acceptable if you harm others. For example, if a doctor gives the patient the wrong diagnosis or medicine this could harm a precious life. When you keep on doing the mistakes repeatedly, your brain will insert this mistake as the correct answer. Therefore, you must be vigilant of every little thing we conduct, so you do not harm others or yourself unintentionally.
A mistake shows that either you need to try harder or that you need to learn a bit farther. Even though mistakes are perfectly regular for us, a mistake is not ever too good.

Answer:
I'm pretty sure the answer is D. "Big Year" birders compete to see more birds than others.
Explanation:
Reasoning being: In Passage 3 the main objective of this event's description is ""<em>Big Year" is a year in which a person attempts to see as many different species of birds as possible within a particular region.</em>"
I think the answer is B however Im just inferring since we can't see the paragraph.
