The World Bank has recently estimated the number of people in absolute poverty in the Third World at around 780 million. Half of them are in South Asia. The other half lives in East Asia, sub-Saharan Africa, Latin America, North Africa and the Middle East. Roughly 80 percent of these poor live in the countryside, mostly as small farmers and landless laborers. Poverty is thus an essentially rural phenomenon.
________ Non-reasoning ________ Reasoning
In the first place, we may start with the strong presumption that Colonel Openshaw had some very strong reason for leaving America. Men at his time of life do not change all their habits, and exchange willingly the charming climate of Florida for the lonely life of an English provincial town. His extreme love of solitude in England suggests the idea that he was in fear of someone or something, so we may assume as a working hypothesis that it was fear of something or someone which drove him from America.

6. Answer the following questions based on the following quotation. On October 1, 2007, S&P 500 closed at 1547 where the quotation of CALL options on S&P 500 was as follows. Those contracts expire in October 2007.
| Strike Price | Open | High | Low | Last | Sett |
| 1540 | -- | -- | -- | -- | 31.70 |
| 1600 | 1.70 | 3.60 | 1.70 | 3.00 | 3.35 |
(a) Which option is in the money?
(b) Decompose the value of 1540 call, $31.7, into intrinsic value and time value.
(c) Again using the call with exercise price of 1540, what would be your cash proceeds if you exercise the option on October 1 (index options are settled by cash)? Assume that both dividends and transaction costs are small enough to be ignored. Based on this answer and answer on (b), does it make sense to exercise an American call before expiration? Explain.
(d) Assume that put-call parity holds for these options (it does not exactly hold since the above options are all American). What should be the value of a PUT on S&P 500 with exercise price of 1600? Assume that the annual risk-free rate is 5%.

(Sig Figs) Iron(III) oxide reacts with carbon
monoxide according to the equation:
Fe2O3(s)+3CO(g)→2Fe(s)+3CO2(g)
A reaction mixture initially contains 22.20 g
Fe2O3 and 14.00 g CO.
The online website said the answer is m = 2.32g ( 3 sig
figs)
While my answer was 2.318 ( 4 sig figs)
Heres my calculations
22.20 g Fe2O3 / 159.69 =
0.13901934999060680067631035130565 mols of
Fe2O3
14.00 g CO / 28.01 = 0.49982149232416993930739021777936 mols
of CO
0.13901934999060680067631035130565 x 3 =
0.41705804997182040202893105391696 mols of
Fe2O3 needed to react with 3 mols of CO
CO is the excess compound so:
0.49982149232416993930739021777936 mols of
Fe2O3 - 0.41705804997182040202893105391696
mols of CO =
0.0827634423523495372784591638624 moles of CO in excess
0.0827634423523495372784591638624 mol co * 28.01g / mol CO =
2.31820402.....
4 sig figs = 2.318g of CO

Over a 17-year period researchers studied a sample of 707 individuals from a single community. They recorded the number of hours each individual spent watching television during adolescence and early adulthood. in later years, they recorded the number of aggressive acts by individuals in the study. Science magazine published the results in 2002 in an article titled "Television Viewing and Aggressive Behavior during Adolescence and Adulthood."
Pick the best description of this study:
A. an observational study to make an estimate or a claim about a population
B. an experiment to establish a cause-and-effect relationship between two variables
C. an observational study of an association between two variables

Why an American option holder chooses the first time, that the time value of option is zero, to exercise the option? Or, in other words, why not choose the last one?
Basically, what is the benefit to exercise early rather than later if time value is 0?
Can Time Value be 0 more than once? or only at expiration?

Pick a period in Western history OR a non-Western traditional society and write about the role of women in that period or society. You could, for example, examine the role of women in ancient Greek society, Roman society, medieval society, and/or in American society in antebellum South or in the industrial North before the Civil War. Or you could examine the role of women in traditional Arabic tribal society, African society, Latin American tribal society, Inuit culture, and so forth. (You can research any one of these topics through the library or by utilizing good online resources; this is a mini research project.) You can focus on one or more than one society, depending on your own interest in the research.
