National income:

National income refers to the income of a country from all the three sectors of the economy in a year. These sectors are primary, secondary, and tertiary. The value of services and goods produced is calculated to find out the national income of an economy.  

In simple words, National income is the income of a whole country in a year.  

National income includes all the following components:

•Salaries and wages

•Rental income

•Interest

•Profits of organizations

•Indirect taxes

•Depreciation

Justification for the correct and incorrect

a.

Rent: This option is incorrect.

Rent is a component of national income but rent is treated as a large component of the national income, not the smallest component.

b.

Interest: This option is incorrect.

Interest is a component of national income, but it is not the smallest component of national income because interest constitutes a portion of national income which is big, not small.

c.

Profits: This option is incorrect.

Profits are the component of national income, but profits are not the smallest components of national income. The profits are the main income which is treated as a large part of the national income.  

d.

Salaries and wages: This option is correct.

Salaries and wages are the smallest components of national income. Salaries and wages are not treated as large components of national income. They constitute a small portion while calculating the national income.

Thus, salaries and wages are the smallest components of national income.

freeborn women in ancient rome were citizens (cives), but could not vote or hold political office. because of their limited public role, women are named less frequently than men by roman historians. but while roman women held no direct political power, those from wealthy or powerful families could and did exert influence through private negotiations. exceptional women who left an undeniable mark on history range from lucretia and claudia quinta, whose stories took on mythic significance; fierce republican-era women such as cornelia, mother of the gracchi, and fulvia, who commanded an army and issued coins bearing her image; women of the julio-claudian dynasty, most prominently livia (58 bc-ad 29), who contributed to the formation of imperial mores; and the empress helena (c.250–330 ad), a driving force in promoting christianity.

women in the ancient greek world had few rights in comparison to male citizens. unable to vote, own land, or inherit, a woman’s place was in the home and her purpose in life was the rearing of children. this, though, is a general description, and when considering the role of women in ancient greece one should remember that information regarding specific city-states is often lacking, is almost always from male authors, and only in athens can their status and role be described in any great detail. neither are we sure of the practical and everyday application of the rules and laws that have survived from antiquity. we do know that spartan women were treated somewhat differently than in other states. for example, they had to do physical training like men, were permitted to own land, and could drink wine.

well considering i can't see the graph, it's probably prices
