What is the central idea of this paragraph ?
dna “fingerprinting” is fairly common in crime‐solving today, but it is a relatively recent technology. it wasn’t until
the 1980’s that scientists realized that they could see differences in people’s dna, but in 1987 the first criminal was
caught using dna evidence, and the landscape of criminal justice was forever changed. today, the innocence project,
a non‐profit organization in new york, uses dna evidence to exonerate people of crimes of which they have been wrongly
convicted. but dna identification isn’t just used to solve crimes. it has successfully reunited family members who were separated
after natural disasters, and has to determine people’s ethnic heritage. dna can also be used to identify the bodies of those
who have died in accidents when there is no other means of identification available.

Which excerpt from shirley chisholm’s speech “equal rights for women” provides support for chisholm’s analysis of how the facts justify her conclusion? `it is true that part of the problem has been that women have not been aggressive in demanding their rights. this was also true of the black population for many years. they submitted to oppression and even cooperated with it. women have done the same thing. `women need no protection that men do not need. what we need are laws to protect working people, to guarantee them fair pay, safe working conditions, protection against sickness and layoffs, and provision for dignified, comfortable retirement. men and women need these things equally. that one sex needs protection more than the other is a male supremacist myth. `it is obvious that discrimination exists. women do not have the opportunities that men do. and women that do not conform to the system, who try to break with the accepted patterns, are stigmatized as ‘‘odd’’ and “unfeminine.” the fact is that a woman who aspires to be chairman of the board, or a member of the house, does so for exactly the same reasons as any man. `as in the field of equal rights for blacks, spanish-americans, the indians, and other groups, laws will not change such deep-seated problems overnight. but they can be used to provide protection for those who are most abused, and to begin the process of evolutionary change by compelling the insensitive majority to reexamine its unconscious attitudes.
