If this is world history, i can answer anything but traditional. so command economy. example: mao ceding in china under the great leap forward. he basically collectivized all farms. so an advantage of it is the government controls the economy. this is beneficial because you get reforms such as land redistribution. a downside is that everything is government owned. a market economy is capitalism, think US. advantage is that supply and demand laws. a disadvantage is that if the economy falls everybody feels it bc the government doesn’t play a role in the economy, for example, the Great depression. mixed is mixing both command and market. example: china after mao, so Deng Xiaoping. he basically allowed Four Economic Zones which allowed public investment into China to rebuild the economy. advantage is that you feel the effects of the free market but the gov still controls everything. a disadvantage is government control
Overall transformation : Ar-H to Ar-R
Named after Friedel and Crafts who discovered the reaction in 1877.
Reagent : normally the alkyl halide (e.g. R-Br or R-Cl) with aluminum trichloride, AlCl3, a Lewis acid catalyst.
The AlCl3 enhances the electrophilicity of the alkyl halide by complexing with the halide.
Electrophilic species : the carbocation (i.e. R +) formed by the "removal" of the halide by the Lewis acid catalyst
The reactive electrophile, the carbocation is prone to rearrangement to a more stable carbocation which will then undergo the alkylation reaction.

Friedel-Crafts reactions are limited to arenes as or more reactive than mono-halobenzenes
Other Lewis acids such as BF3, FeCl3 or ZnCl2 can also be used
Other sources of carbocations can also be used:
from loss of water from alcohols treated with acid such as H2SO4
from the protonation of alkenes by acid such as H2SO4
Alkylation products can also be obtained by the reduction of Friedel-Crafts acylation products
I believe the correct answer from the choices listed above is option A. Political parties most often try to gerrymander voting districts in order to gain a political advantage. Gerrymandering can be best defined as <span>drawing political boundaries to give your party a numeric advantage over an opposing party. Hope this answers the question.</span>
