उत्तर : 3. "Congress grants funds to federal agencies."
व्याख्या :

Answer: C) Congress grants funds to federal agencies. Explanation: Appropriations are annual decisions made by Congress about how the federal government spends some of its money. In general, the appropriations process addresses the discretionary portion of the budget – spending ranging from national defense to food safety to education to federal employee salaries, but excludes mandatory spending, such as Medicare and Social Security, which is spent automatically according to formulas.   Hence, congress grants funds to federal agencies and programs during the appropriations process.

He is from the Midwest, but narrates the story after it takes place in the East. As such, he is an outsider, and tends to judge what he experiences in the East based on his midwestern ideas and values.   Nick makes an effort to assure the reader that he is nonjudgmental and completely honest. This is ironic, because he is very judgmental and opinionated.

उत्तर :
व्याख्या :

Matching blood group before marriage is important. This is to prevent Rh incompatibility. Rh incompatibility can lead to erythroblastosis fetalis (Hemolytic disease of the newborn-HDN). Fetal RBC gets destroyed & newborn may get severe anaemia, jaundice. This jaundice is more severe than Physiological jaundice ( which is the most common and will usually resolve on its own).   In very severe form, a fetus may die due to heart failure. This is mediated by the antigen-antibodies reaction. Transfer of maternal antibodies across the placenta occurs. This happens when Rh +ve man marries Rh-ve lady.    So Rh +ve man should try to avoid marrying Rh-ve lady.   Matching blood groups for marriage :: Boy : A = Girl : A & AB  Boy : B = Girl : B & AB  Boy : O = Girl : O, A, B & AB  Boy : AB = Girl : AB  Boy : Rh+ve = Girl : Rh+ve  Boy : Rh-ve = Girl : Rh+ve & Rh-ve.    Blood groups that do not match for marriage :: Boy : A = Girl : O & B  Boy : B = Girl : O & A  Boy : AB = Girl : O, A & B  Boy : Rh+ve = Girl : Rh-ve.
