Melissa: we must become more flexible if we are to meet our personnel needs and maximize efficiency. in the past, we simply hired as many full-time employees as we thought we needed. but, this focus has caused us to lose many valuable employees. we should offer flextime and job sharing options to us keep and attract talented employees.
jennifer: alternatives to traditional job design approaches can lead to significant cost savings. we are expected to have 500 more employees than our current facility allows next year, but my analysis reveals 600 of our employees could telecommute. therefore, we can avoid costly actions such as moving our offices or building extensions if these workers became telecommuters. job sharing can also reduce facility costs as well as payroll costs. which of the following, if true, would strengthen melissa's argument?

light-year  

the distance that light travels in a vacuum in one year, equal to about 9.46 trillion km (5.88 trillion mi). light-years are used in measuring interstellar and intergalactic distances.  

parsec  

a unit of distance used in astronomy, equal to about 3.25 light years (3.08 × 1016 meters).  

parallax  

the apparent angular displacement of a celestial body due to its being observed from the surface instead of from the center of the earth (diurnal parallax or geocentric parallax) or due to its being observed from the earth instead of from the sun (annual parallax or heliocentric parallax)  

absolute magnitude  

the magnitude (brightness) of a celestial object as it would be seen at a standard distance of 10 parsecs.  

apparent magnitude  

the magnitude of a celestial object as it is actually measured from the earth.  

redshift  

an increase in the wavelength of radiation emitted by a celestial body as a consequence of the doppler effect.  

the great thing about your imagination is that it doesn't have to make sense! if i were you i would be stuck in space, no communication with earth travelling around and around, you can only guess how long its been since your communication broke down. you land on an undiscovered planet, you do a scientific investigation examining the elements and conditions. you come across alien lifeforms.  

best of luck!
