In many parts of the world, there is a rock layer rich in the metal iridium. Iridium is very rare on Earth, but it is relatively common in meteorites and other debris that comes from outer space. All occurrences of this iridium layer are from the same geologic epoch, at the very end of the Cretaceous. Most of the fossils in rock layers below the iridium layer, including dinosaur fossils, do not appear in layers above the iridium layer.

Based on this evidence from the rock and fossil record,
A.
meteoroids and other space debris did not impact the Earth at the end of the Cretaceous.
B.
an asteroid impact likely caused a mass extinction at the end of the Cretaceous.
C.
meteorites and other space debris no longer contain the metal iridium.

Perform an online or offline search, and choose a technology firm near your location. You must then call and speak to someone from the firm's Human Resources department (preferably the HR manager) and conduct a brief (15- to 20-minute) interview with them. During the interview, you need to ask questions about the company's core functions, the different types of jobs available in the company, a list of qualities that the company expects from its employees, and so on. In other words, your questions should cover the points that the HR department would include in the company's Code of Conduct Manual. You should keep a record of all the answers and write a summary of what you have learned. Alternatively, if you do not find a technology firm near your location, or if the HR manager is unwilling to have a sit-down interview, you could find a company online and correspond with the manager through email with the help of a questionnaire.
