Final answer:
To draw the linear arrangement according to the given rules, place R first and S second to honor the consecutive display rule, follow that with an unspecified item in third place, and then Q in the fourth position.
Step-by-step explanation:
The question you've asked about drawing the linear arrangement with the conditions given can be translated into a simple display sequence of hypothetical items or subjects that are to be arranged in a specific order based on the rules provided. Given the rules "If Q is displayed fourth, then R must be displayed first" and that "R and S are displayed consecutively," we can infer the following arrangement:
- R
- S
- An unspecified item
- Q
As 'R' must be displayed first and 'R' and 'S' must be consecutive, 'S' would logically follow 'R'. Q, which is specified to be fourth, would follow after two other unspecified items. Since one of the unspecified items is in the second place and must not disrupt the consecutive placement of 'R' and 'S', the third item can be any item that is not 'Q', 'R', or 'S'. The fourth position is designated for 'Q' based on the rule.
