5. Streptococcus mutans, the bacterium that causes tooth decay, is transmitted almost exclusively from mother to child. This transmission mode allows it to be traced back thousands of years through its DNA to one of several distinct lineages. Tracking the DNA in this manner would not be possible if it were transmitted more easily from person to person.

Which of the following is most strongly supported by the passage?

a) Mothers can be blamed for tooth decay in children.

b) Streptococcus mutans can be classified according to lineage.

c) If it were transmitted from father to child, Streptococcus mutans would not be traceable.

d) Bacteria could not be traced if it had no DNA.

e) Tooth decay only occurs among humans.

6. Marketing Director: For our new computer to be profitable, it must both be accessible to a large number of purchasers and introduce significant new innovations over the previous model. However, the cost of the hardware to make the computer much more advanced than its predecessor will almost certainlynecessitate a price point far above what almost all of our potential customers can afford.

The claims, if true, most strongly support which of the following conclusions?

a) The company should work to convince consumers that the innovations in the new model justify a significantly higher price point.

b) A computer model that has some, but not all, of the proposed innovations and that is only slightly more expensive that the current model is more likely to be successful.

c) The new computer is unlikely to be a profitable model for the company.

d) Reducing the price point of the proposed model will definitely prevent the company from making the technological innovations required for the model to be profitable.

e) Price and innovation are the two most important considerations in computer purchases.
