The Log4j vulnerability (CVE-2021-44228) demonstrated: 

Consider the following information (Figure 2) concerning federal taxes:  (Figure 2) Assume the federal standard deduction is $15,000 and the federal personal exemption is $0. Determine how much Cindy owes in federal taxes if she is single and earns $85,525 per year.

Consider the following information (Figure 5) concerning state taxes in West Virginia: (Figure 5) Determine how much Jerry owes in West Virginia state taxes if he makes $25,000 gross salary per year. Assume he is single and that he will only use the standard deduction and personal exemption.

Complete the following passage with the best answers.  Some answers may be used more than once, some may not be used.   The strength and concentration of acids and bases can be measured in multiple ways.  Perhaps the simplest, oldest, and most common methods involve the use of pH 1)____________________, which change color in the presence of acid or base.  One type is called 2)____________________ paper, which generally changes to blue in the presence of base, and pink (or red) in the presence of acid.  Another type, which goes by the generic name of 3)_________________________ uses several different compounds which change color at different pH values, generating a spectrum of different colors and allowing a more accurate estimate of the pH of the solution.  For even more precise results, a digital 4)________________________ can be used, which is an electronic instrument with an electrode that is immersed in the solution to give a digital readout of pH.  Such instruments do require frequent calibration, however.  A different sort of measure involves an actual stoichometric experiment — in a 5)_______________________, a solution with a very precisely known concentration is reacted with the unknown acid or base until the exact point of complete reaction is reached, at which point the volume and concentration are used to calculate the concentration of the unknown.  In such an experiment, a common visual indicator known as 6)________________________ can be used, which changes color from clear to a purple-pink color very close to neutral pH, with the pink color seen in the basic pH range and clear when the solution is acidic.

Which of the following molecules have a net dipole moment?  Choose all that apply.
