adkikani,
i think, your understanding of argument is little different. See what argument says:
More and more law firms specializing in corporate taxes are paid on a contingency-fee basis. Under this arrangement, if a case is won, the firm usually receives more than it would have received if it had been paid on the alternate hourly rate basis. If the case is lost, the firm receives nothing. Most firms are likely to make more under the contingency-fee arrangement
As per argument:
1. More number of law firms specialized in corporate taxes are paid on contingency fee basis.
2. Contingency fee basis= If case is won, Firm will receive money else firm receives nothing.
3. Alternate Hourly Basis= Firm receives money on hourly basis as long as case is running.
4. As compare to Hourly basis, Firms receives more money in Contingency fee arrangement if case is won.
Conclusion/Claim: Most firms are likely to make more money under Contingency fee arrangementNow you have to strengthen the argument. How can we strengthen argument? See scope of passage. We have to support contingency fee arrangement.
Option A says
Quote:
Firms that work exclusively under the hourly rate arrangement spend, on average, fewer hours on cases that are won than on cases that are lost.
-- Hourly rate arrangement is making money in any case (won or lost). Under this arrangement, if some firm won case in 40 hours they will get paid for 40 hours. If that firm lose case in 80 hours, it will get paid for 80 hours. It is just explaining "Hourly fee arrangement" but not helping for "contingency fee arrangement"
Option D:
Quote:
Since the majority of firms specialize in certain kinds of cases, they are able to assess accurately their chances of winning each potential case.
As per passage under "contingency fee arrangement" firms get more money. So if firm already knows that it will win case then obviously firm will go for "contingency fee arrangement" because it will be getting more money from this arrangement.
Take an example of property which is worth of $10 million. Some firm knows that if it run case, it will win case.
Situation 1: if you run case and u win case then u will get 10% of property value. If u lose case u wont get anything. (Contingency Fee Arrangement)
Situation 2: if you run case under hourly fee arrangement, u lose it or win it, your fee is $200 per hour. No matter what will be the result but you will be paid hourly.
Which arrangement u would like to chose ?
