Gerrymandering refers to the targeted redrawing of election constituencies so as to benefit a particular party. This is especially important where the electoral system is "first past the post" in each constituency (i.e. one winner is selected in each constituency based on a majority of votes won) and where there is no other provision for proportional representation (as for example in the German system). For a simple illustration of gerrymandering, if a region consists of districts 1, 2, 3, ..., 9 with districts 1, 2, 3, 4, 5, 6 favouring party P and 7, 8, 9 favouring party Q, then grouping of districts to constituencies as {1,2,3}, {4,5,6}, {7,8,9} will give two seats to party P and one seat to party Q, whereas the grouping {1,2,7}, {3,4,8}, {5,6,9} will give all three seats to party P, as they will secure a majority in each constituency. Which of these statements can be deduced from the above?
The question asks to deduce a statement from the provided text about gerrymandering. Gerrymandering is defined as the intentional manipulation of electoral district boundaries to gain an advantage for a particular political party.
Let's evaluate each statement based on the provided text:
Reasoning: The text explicitly defines gerrymandering as "the targeted redrawing of election constituencies so as to benefit a particular party." This statement is a direct restatement of the definition and is therefore deducible.
Reasoning: The text mentions gerrymandering is important where the system is "first past the post" and "where there is no other provision for proportional representation." It does not state that proportional representation becomes impossible; rather, it highlights the conditions where gerrymandering is particularly effective due to the absence of PR.
Reasoning: The provided text explains what gerrymandering is and illustrates its effect. It does not offer any advice or strategies on how political parties can counteract it.
Reasoning: The example clearly demonstrates that the grouping of districts has a significant impact on the seat allocation. In the example, different groupings lead to drastically different outcomes (2 seats for P vs. 3 seats for P), which is the opposite of proportional representation and shows a substantial impact.
Based on the analysis, only the first statement can be directly deduced from the information provided in the text. The definition of gerrymandering directly supports this conclusion.
