Input: Article: Modern electrification systems take AC energy from a power grid which is delivered to a locomotive and converted to a DC voltage to be used by traction motors. These motors may either be DC motors which directly use the DC or they may be 3-phase AC motors which require further conversion of the DC to 3-phase AC (using power electronics). Thus both systems are faced with the same task: converting and transporting high-voltage AC from the power grid to low-voltage DC in the locomotive. Where should this conversion take place and at what voltage and current (AC or DC) should the power flow to the locomotive? And how does all this relate to energy-efficiency? Both the transmission and conversion of electric energy involve losses: ohmic losses in wires and power electronics, magnetic field losses in transformers and smoothing reactors (inductors). Power conversion for a DC system takes place mainly in a railway substation where large, heavy, and more efficient hardware can be used as compared to an AC system where conversion takes place aboard the locomotive where space is limited and losses are significantly higher. Also, the energy used to blow air to cool transformers, power electronics (including rectifiers), and other conversion hardware must be accounted for.

Now answer this question: What is the main action AC and DC systems have to deal with?

Output: converting and transporting

Input: Article: Three main parades take place during Carnival. The first is held on the first day, during which the "Carnival King" (either a person in costume or an effigy) rides through the city on his carriage. The second is held on the first Sunday of the festival and the participants are mainly children. The third and largest takes place on the last day of Carnival and involves hundreds of people walking in costume along the town's longest avenue. The latter two parades are open to anyone who wishes to participate.

Now answer this question: Which of the festivals is comprised of participants who are mainly children?

Output: The second

Input: Article: Opposition to the union mounted among some of Syria's key elements, namely the socioeconomic, political, and military elites. In response to Syria's worsening economy, which Nasser attributed to its control by the bourgeoisie, in July 1961, Nasser decreed socialist measures that nationalized wide-ranging sectors of the Syrian economy. He also dismissed Sarraj in September to curb the growing political crisis. Aburish states that Nasser was not fully capable of addressing Syrian problems because they were "foreign to him". In Egypt, the economic situation was more positive, with a GNP growth of 4.5 percent and a rapid growth of industry. In 1960, Nasser nationalized the Egyptian press, which had already been cooperating with his government, in order to steer coverage towards the country's socioeconomic issues and galvanize public support for his socialist measures.

Now answer this question: How was Syria's economy fairing under the arrangement?

Output:
worsening
