A city planner is using simulation software to study crowd flow out of a large arena after an event has ended. The arena is located in an urban city. Which of the following best describes a limitation of using a simulation for this purpose? a) The model used by the simulation software cannot be modified once the simulation has been used.
b) The model used by the simulation software often omits details so that it is easier to implement.
c) Running a simulation requires more time to generate data from trials than observing the crowd exiting the arena at various events.
d) Running a simulation requires a large number of observations to be collected before it can be used to explore a problem.

d)

Explanation:

The main limitation of simulations is that running a simulation requires a large number of observations to be collected before it can be used to explore a problem. In a real life situation there are thousands of variables to take into consideration which can drastically affect the way that the situation unfolds at any given time. Therefore, in order to replicate/simulate such a scenario all of these variables need to be taken into consideration. This data can take a large amount of time to observe and collect in order to implement into the simulation so that it provides an accurate depiction of the problem.

a  social news website  is an  internet  website  that features  user-posted stories. such stories are ranked based on popularity, as voted on by other users of the site or by website administrators. users typically comment online on the news posts and these comments may also be ranked in popularity. since their emergence with the birth of  web 2.0, social news sites have been used to link many types of information, including news, humor, support, and discussion. all such websites allow the users to submit content and each site differs in how the content is moderated. on the  slashdot  and  fark  websites,  administrators  decide which articles are selected for the front page. on  reddit  and  digg, the articles that get the most votes from the community of users will make it to the front page. many social news websites also feature an online comment system, where users discuss the issues raised in an article. some of these sites have also applied their voting system to the comments, so that the most popular comments are displayed first. some social news websites also have a  social networking  function, in that users can set up a user profile and follow other users' online activity on the website.
