Read the excerpt from "Tools of the Spymaster." 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. Which statement includes explicit information from the excerpt?

A. Washington asked James Jay to invent a form of invisible ink.

B. Washington only knew about invisible ink that required heating.

C. James Jay was a doctor who had knowledge of chemistry.

D. James Jay created an invisible ink system that required two chemicals.

Arturo · Answer 1

Answer: I would contend that the right answer is the D) James Jay created an invisible ink system that required two chemicals.

Explanation: Just to elaborate a little on the answer, it can be added that it is not explicitly said that Washington asked Jay to invent that form of invisible ink, only that it was the type of ink that he was seeking. In addition, it is not explicitly said that Washington only knew about invisible ink that required heating, only that Jay's ink was not visible through heating. Finally, it is not explicitly said that James Jay was a doctor. Therefore, the only statement that includes explicit information from the excerpt is the one offered in option D: Jay did create an invisible ink system that required using two chemicals-one to write the message and another one to read it.
