Scholars generally estimate subscribers to Freedom z Journal (1827-1829), the United States" first African American newspaper, at around 800. based on subscriptions to The Rights of AIL an African American newspaper founded in 1829 as a successor to Freedom s Journal by a former editor of that newspaper But Gross argues that many more than 800 readers probably subscribed to Freedom X Journal because many of its subscribers, dissatisfied with the direction ultimately taken by the paper, refused to subscribe to The Rights of All. In any case, the figure of 800 subscribers would make the circulation of Freedom s Journal close to that of other weekly papers of the time Its number of readers, however, would have been much larger: copies were often shared. and African American organizations subscribed to Freedom s Journal, providing nonsubscribers access to the paper
Which of the following, if true, would most lend to undermine Gross's argument mentioned in the highlighted portion of the passage?

C

Larvae of many marine invertebrate species delay their metamorphosis into juveniles when cues signaling an appropriate juvenile environment are absent, thereby increasing then* likelihood of thriving as juveniles and of ultimately reaching adulthood Nevertheless, delayed metamorphosis has potential costs for juveniles including reduced growth and increased mortality Nearly all evidence of such costs involves species whose larvae do not feed but rather subsist on stored nutrients, indicating that insufficient energy reserves may be an underlying cause of these costs. Supporting this hypothesis are laboratory studies showing that in a certain bryozoan. the prolonged larval swimming that results from delayed metamorphosis is associated with size reductions in the juvenile feeding organ (the lophophore) and that one factor influencing the size of juveniles of certain barnacle species is how long larvae delay metamorphosis However, other studies show that while significantly fewer juvenile Capitella worms survived to adulthood when metamorphosis had been delayed, prolonged larval swimming had no significant effect on juvenile size, suggesting, perhaps, that in some species, factors other than insufficient energy reserves account for the negative effects of the larval stresses that result from delayed metamorphosis.
The "hypothesis" implies that compared to marine invertebrate larvae that subsist on stored nutrients, marine invertebrate larvae that feed are less likely to
