Final answer:
The sentence that requires a citation is the factual claim about the number of executions in a.Texas from 1970 to 1979. This sentence should be supported by a credible source.
Step-by-step explanation:
The sentence that requires the use of a citation is: "Thirty-seven people were executed in the state of Texas from 1970 to 1979." This statement presents a factual claim that can be verified with data and therefore should be supported by a reference to a credible source.
Conversely, the other sentences reflect personal opinions or experiences that don't require citation in most academic contexts.
The controversy surrounding the death penalty involves debates on whether or not certain methods of execution violate the Eighth Amendment's ban on "cruel and unusual punishments."
The Supreme Court's decisions on the constitutionality of the death penalty have evolved over time, influencing the application of capital punishment in various states.
It's also important to note the influence of public opinion and the impact of DNA evidence in questioning the integrity of the death penalty system.
For instance, the Supreme Court case of Furman v. Georgia found the arbitrary imposition of the death penalty unconstitutional, leading to a moratorium on executions until the Gregg v. Georgia decision.
More recently, debates over lethal injection and other methods have highlighted ongoing concerns about the application of capital punishment in the United States.
