3. (C) The relevant information is located in Table 2, but there is no entry in the table for 90 dB. However, 90 dB is between 60 dB and 120 dB. The most likely conclusion, then, is that the corresponding entry in –Š‡ ϔ‹”•–…‘Ž—ǡ ‹ˆ ‘‡ ‡š‹•–‡†ǡ ™‘—Ž† „‡ between 12.0 and 19.0 seconds.

4.

4. (J) Table 1 shows the amount of

aerosanizen needed to neutralize the quantity of malodorzane at various temperatures. So, the data in that table would provide information about how the temperature of the protocrud affects the rate of malodorzane production.
