17.A RESULT, FACTORS SUCH AS… AND ATTITUDES TO CHILDREN 
HAVE BEEN ELIMINATED 
Keywords: factors, attitudes to children, eliminated 
In paragraph 2, it is stated that in a “long-term study carried out in Nicaragua”, factors such as “the 
fact that a woman has had an education may simply indicate her family‟s wealth or that it values its 
children more highly” were eliminated. “Value children more highly” can be referred to as “attitudes 
to children”, so the other factor is “family wealth”.

18.AND IT HAS BEEN SHOWN THAT….. CAN IN ITSELF IMPROVE 
INFANT HEALTH AND SURVIVAL. 
Keywords: infant health, survival, improve 
In paragraph 2, we are told the factor which can improve children‟s health and survival: “…teaching 
reading to poor adult women, who would otherwise have remained illiterate, has a direct effect on 
their children‟s health and survival.” So, the infants of mothers who are literate, have better chances 
of having good health and surviving. The answer is: maternal literacy.

20.BEFORE THE NATIONAL LITERACY CRUSADE , ILLITERATE 
WOMEN HAD APPROXIMATELY THE SAME LEVELS OF INFANT 
MORTALITY AS THOSE WHO HAD LEARNT TO READ IN PRIMARY 
SCHOOL 
Keywords: before, illiterate women, same levels, infant mortality, primary school 
In paragraph 5: “In the late 1970s, the infant mortality rate for the children of illiterate mothers was 
around 110 deaths per 1000 live births… For women educated in primary school, however, the infant 
mortality rate was significantly lower, at 80 per 1000.” So the levels of infant mortality are different. 
+ infants = very young children
