Example Input: Dari (Dari: (dai)) or Dari Persian ( Farsi-ye Dari (fsije dai)) or synonymously Farsi ( Farsi (fsi)) is the variety of the Persian language spoken in Afghanistan. Dari is the term officially recognized and promoted since 1964 by the Afghan government for the Persian language, hence, it is also known as Afghan Persian in many Western sources. This has resulted in a naming dispute. Many Persian speakers in Afghanistan prefer and use the name 'Farsi' and say the term Dari has been forced on them by the dominant Pashtun ethnic group as an attempt to distance Afghans from their cultural, linguistic, and historical ties to the Persian-speaking world, which includes Iran and Tajikistan.
Example Output: what's the difference between farsi and dari

Example Input: Direct market access (DMA) is a term used in financial markets to describe electronic trading facilities that give investors wishing to trade in financial instruments a way to interact with the order book of an exchange. Normally, trading on the order book is restricted to broker-dealers and market making firms that are members of the exchange. Using DMA, investment companies (also known as buy side firms) and other private traders use the information technology infrastructure of sell side firms such as investment banks and the market access that those firms possess, but control the way a trading transaction is managed themselves rather than passing the order over to the broker's own in-house traders for execution. Today, DMA is often combined with algorithmic trading giving access to many different trading strategies. Certain forms of DMA, most notably 'sponsored access,' have raised substantial regulatory concerns because of the possibility of a malfunction by an investor to cause widespread market disruption.
Example Output:
