Answer the following question given this paragraph: Mars is the easiest planet to observe. As a result, it has been studied more than any other planet besides Earth. People can stand on Earth and observe the planet through a telescope. We have also sent many space probes to Mars. In April 2011, there were three scientific satellites in orbit around Mars. The rover, Opportunity, was still moving around on the surface. No humans have ever set foot on Mars. NASA and the European Space Agency have plans to send people to Mars. The goal is to do it sometime between 2030 and 2040. The expense and danger of these missions are phenomenal. Q: Which other planet in the solar system is the easiest to observe from earth? A:
OPTIONS:
- Pluto
- Mercury
- Jupiter
- mars
mars

Answer the following question given this paragraph: Thiols (also called mercaptans), which are sulfur analogs of alcohols, have the general formula RSH. Methanethiol (also called methyl mercaptan), has the formula CH3SH. Ethanethiol (ethyl mercaptan) is the most common odorant for liquid propane (LP) gas. The mild oxidation of thiols gives compounds called disulfides. Q: The mild oxidation of thiols gives compounds called what? A:
OPTIONS:
- carbonates
- halides
- dioxides
- disulfides

Answer: disulfides

Answer the following question given this paragraph: Mass spectrometry today is used extensively in chemistry and biology laboratories to identify chemical and biological substances according to their mass-to-charge ratios. In medicine, mass spectrometers are used to measure the concentration of isotopes used as tracers. Usually, biological molecules such as proteins are very large, so they are broken down into smaller fragments before analyzing. Recently, large virus particles have been analyzed as a whole on mass spectrometers. Sometimes a gas chromatograph or high-performance liquid chromatograph provides an initial separation of the large molecules, which are then input into the mass spectrometer. Q: Mass spectrometry today is used extensively in chemistry and biology laboratories to identify chemical and biological substances according to their ratios of what? A:
OPTIONS:
- ph to charge
- volume to charge
- mass to volume
- mass-to-charge
mass-to-charge
