Government official: Currently many business travelers rely on a one-hour flight between the cities, but complain about congestion and delays at the airport. The new high-speed railway between Hamport and Dudley, Aplandia's two major financial hubs, will be able to make the same trip in slightly less than three hours. Given this option, many who fly between the two cities during the week will choose the railway, since it will allow them to travel between the city centers in less time than a flight with the expected delays plus the commute to and from airports would take.

A study of young children's ability to learn foreign languages found that those with parents who read them more than one book per week in their native language were 75% more proficient in the foreign languages that they learned than children whose parents read them one book per week or less. A secondary finding of the study was that children's ability to remember new vocabulary in a second language drops off sharply after the age of 6, when it becomes 75% more difficult to retain new words learned in the second language.Assuming the statements above are true, which of the following can be inferred from them?

While antibiotics have done inestimable good to humankind over the last seventy years, there are several drawbacks to using antibiotics that, until recently, have been overlooked. The human microbiome, which consists of the trillions of bacteria that reside in each person's body, is essential to good health. Specifically, the body contains and requires both “good” and “bad” bacteria. It is when the proper equilibrium between the “good” bacteria and the “bad” bacteria is disrupted that a number of health issues can emerge. Nonetheless, antibiotics indiscriminately kill both the “good” and the “bad” bacteria, so each course of antibiotics should be followed by a treatment that ___________________________________. Which of the following most logically completes the argument above?
