Furthermore , if the problem in part ( a ) is changed so that activity E cannot start until both C and D are completed but that F can start after D alone is completed , the order in the new sequence can be indicated by the addition of a dummy activity Y , as shown in part ( c ) . Now that both countries are getting richer , their common slogan is , " make money , not war . However , it shall aggregate the routes it originates in its outbound announcements towards both peer providers and customers . In Fig. 10-1 ( a ) , the elimination of activity C would mean that both activities B and D would be identified as being between nodes 1 and 3 . This is due to the fact that both variables are giving much the same information , and in the model in which they both appear they share the burden of predicting the response , but when they appear individually they have to do double duty . Where previous work had identified brain regions , each comprised of millions of nerve cells , that both responded to alcohol and contained type 1 benzodiazepine receptors , microiontophoresis allowed Criswell to determine at the level of the individual neuron whether presence of a type 1 benzodiazepine receptor was associated with response to alcohol . No subject can count towards both degrees . The use of dual credit - - courses that can be used toward both degrees - - enables acceleration of the program , reducing the total enrollment of the student by one semester . It is likely that there will be at least two openings on the Court in the near future-there is speculation that both Chief Justice Rehnquist and Justice O'Connor wish to retire soon-and the topic of who will fill those slots is the subject of frequent and heated debate . For example , knowledge that Y can be validly inferred from X does not license one to believe Y if one believes X ; it may be more rational to abandon one 's belief in X , or to take up a sceptical position towards both X and Y ( see Harman 1984 ) .
