Original sentence: Faced with the rise of the PCI, many centrist politicians and businessmen began to think how to avoid the possibility of a Communist victory that could turn Italy into a Soviet-aligned State.Giulio Andreotti's subsequent attempt to form a classic centre-left government with the Socialists failed, and a new general election was called for 1979.However this process, called National Solidarity, was dramatically ended by the terrorist attacks of the Red Brigades, which saw the kidnapping and murder of former-PM Aldo Moro.The DC leadership thought to gradually involve the Communists in governmental policies so as to moderate their aims, as had been done with the Socialists previously.The country was shocked by these killings, and the Communists returned to full opposition.The man who was chosen to lead this attempt did not belong to the leftist wing of the DC, as had happened with the PSI moderation effort, but the moderate leader and former-PM Giulio Andreotti, so as to balance the situation and calm the markets.Two new leftist forces made their debut in this election: the ultra-liberal Radical Party, which had led a successful referendum on divorce, and the far-left Marxist and Maoist Proletarian Democracy
Edited sentence: Faced with the rise of the PCI, many centrist politicians and businessmen began to think how to avoid the possibility of a Communist victory that, in their perception, could turn Italy into a Soviet-aligned State.Giulio Andreotti's subsequent attempt to form a centre-left government with the Socialists failed, and a new general election was called for 1979.However this process, called National Solidarity, was dramatically ended by the activities of the Red Brigades, which saw the kidnapping and murder of former-PM Aldo Moro.The Communists thereafter returned to full opposition.The DC leadership decided to involve the Communists in governmental policies very gradually so as to moderate their aims, as had been done with the Socialists previously.The man who was chosen to lead this attempt did not belong to the leftist wing of the DC, as had happened with the PSI moderation effort, but the moderate leader and former-PM Giulio Andreotti, so as to balance the situation and set the business constituency at ease.Two new leftist forces made their debut in this election: the liberal Radical Party, which had led a successful referendum on divorce, and the Marxist and Maoist Proletarian Democracy
