Another major park is the Esplanade, located along the banks of the Charles River. The Hatch Shell, an outdoor concert venue, is located adjacent to the Charles River Esplanade. Other parks are scattered throughout the city, with the major parks and beaches located near Castle Island; in Charlestown; and along the Dorchester, South Boston, and East Boston shorelines.

Input: Cardinal (Catholicism)
In accordance with tradition, they sign by placing the title "Cardinal" (abbreviated Card.) after their personal name and before their surname as, for instance, "John Card(inal) Doe" or, in Latin, "Ioannes Card(inalis) Cognomen". Some writers, such as James-Charles Noonan, hold that, in the case of cardinals, the form used for signatures should be used also when referring to them in English. Official sources such as the Archdiocese of Milwaukee and Catholic News Service say that the correct form for referring to a cardinal in English is normally as "Cardinal [First name] [Surname]". This is the rule given also in stylebooks not associated with the Catholic Church. This style is also generally followed on the websites of the Holy See and episcopal conferences. Oriental Patriarchs who are created Cardinals customarily use "Sanctae Ecclesiae Cardinalis" as their full title, probably because they do not belong to the Roman clergy.

Why do Oriental Patriarchs sign this way?
Output: because they do not belong to the Roman clergy

Input: Political party
In one-party systems, one political party is legally allowed to hold effective power. Although minor parties may sometimes be allowed, they are legally required to accept the leadership of the dominant party. This party may not always be identical to the government, although sometimes positions within the party may in fact be more important than positions within the government. North Korea and China are examples; others can be found in Fascist states, such as Nazi Germany between 1934 and 1945. The one-party system is thus usually equated with dictatorships and tyranny.

In what systems is the political party allowed to legally hold effective power?
Output: one-party systems
