IMO C

Option D: trading greater volumes means lower transaction since a single transaction now contains more stocks.

We need to explain two seemingly contradictory trends:
- A decrease in the number of people involved in stock market trading
- An increase in the actual number of trades


A. Trading in bonds greatly increased in the past year
This doesn't explain the increase in stock trades or the decrease in stock traders.

B. The increase in the number of professional traders was greater than the decrease in the number of private traders
This only tells us the proportion of the number of professional vs private traders amongst the decreased count of total traders. No matter what the proportion is, the overall number of traders still decreased so it doesn't matter if a certain type of traders actually increased. It also does nothing to explain wny the number of trades actually went up.

C. Although an economy in crisis keeps most people away from the stock market, it provides an excellent opportunity for professional traders willing to take risks by becoming even more active in the markets than usual.
This explains both trends: fewer people overall (as most stay away), but more trades (as professionals become more active). => Keep this for now

D. A new, advanced online interface for purchasing and selling stocks came into use this past year, allowing subscribers to trade in greater volumes than ever before.
This could explain the increase in trades, but doesn't explain why fewer people are involved.

E. Most people sold their stocks for fear the stock market would crash.
This might explain a temporary increase in trades, but doesn't explain the continued high trading volume or why fewer people are involved overall.


Option C provides the best explanation for both observed trends. It explains why the number of people involved decreased (most people staying away due to the crisis) and why the number of trades increased (professional traders becoming more active).

Therefore, the best answer is C.

Bunuel can you please post the official explanation?

cc: KarishmaB chetan2u can anyone pls help me understand why D is the better choice than C?

During turbulent times, stocks are seen as a riskier investment. This past year, the number of people involved in stock market trading declined compared to previous years, though the actual number of trades went up.

Which of the following, if true, could best explain the simultaneous increase in trades and decrease in number of people involved in trading?


A. Trading in bonds greatly increased in the past year

B. The increase in the number of professional traders was greater than the decrease in the number of private traders

C. Although an economy in crisis keeps most people away from the stock market, it provides an excellent opportunity for professional traders willing to take risks by becoming even more active in the markets than usual.

E. Most people sold their stocks for fear the stock market would crash.

I would have chosen (C) here without a second thought. The test maker obviously had something else in mind and I am not sure what it is. Only official solution can tell.
It explains fewer people and more trades by the professionals. This option is exactly what I expected when I read the argument. More active means more participation in the market so more trades certainly makes sense.

(D) talks about bigger trade volumes, not necessarily more trades. The advanced interface could allow bigger orders and hence greater volumes. Doesn't say much about the actual number of trades - if I am to be picky. Anyway that interface would be available to all so why did fewer people participate - it doesn't clarify that either.

It is option C in my opinion. Only option that caters to the simultaneous increase and decrease.

So, the number of people involved in trading went down but the number of trades went up, it won't take a genius to figure out how's that possible:
People left are trading more volumes simple.! (b/w do you have any inside source :D) [Strict hush hush haan.!] ;)

A. Trading in bonds greatly increased in the past year
Not in line with our pre-thinking approach.
B. The increase in the number of professional traders was greater than the decrease in the number of private traders
Are professional and private traders the only people who do trading.? I hope you understand what I am trying to imply. (work that grey cells of yours) :D
C. Although an economy in crisis keeps most people away from the stock market, it provides an excellent opportunity for professional traders willing to take risks by becoming even more active in the markets than usual.
Becoming more active is not proportional to trading more stocks.
D. A new, advanced online interface for purchasing and selling stocks came into use this past year, allowing subscribers to trade in greater volumes than ever before.
Ohkay. So you want to be a stockbroker. In line with our pre-thinking.
E. Most people sold their stocks for fear the stock market would crash.
Do selling of stocks make the number of stocks go up.? I don't know. I am not an Expert. So why it is expecting me to be one.?
