Recent incursions by deep-sea fishermen into the habitat of the Madagascan shrimp have led to a significant reduction in the species population. With the breeding season fast approaching, the number of shrimp should soon begin to increase. Nonetheless, the population should not return to the levels before the fishing boats arrived. Because this trend is expected to continue over the next several years, the Madagascan shrimp will quickly become an endangered species.





The passage assumes that reduction in the population of the Madagascan shrimp linked with the recent incursions by deep-sea fishermen. According to the information given in the passage, the number of shrimp should soon begin to increase because of the breeding season, but it will never reach the levels before the fishermen arrived. It is stated that trend will extrapolate over the next years, therefore Madagascan shrimp will quickly become an endangered species. This consequence is quite consistent, but the arguments leading to this conclusion are not cogent and inviolable.

First of all, the author of the passage doesn't provide readers with the evidence explaining why intervention by deep-sea fishermen into the habitat of the Madagascan shrimp stated as a main reason of the decline in population of this sea animals. Indeed, there are number of possible reasons might cause this reduction: epidemic in the population, changing of the sea environment, pollution of the sea. Thus, to prove that fishermen's incursion to the "home «of the Madagascar shrimp is the cause of the reduction in the number of shrimps, additional investigation must be done.

Secondly, there is no any evidence corroborating the statements that population of Madagascar shrimp will never return to return to the levels before the fishing boats arrived and this trend will continue over the next several years. Such a conclusion requires special information, including cerebral, elaborate, detail analysis of the situation and science based calculation. Hence, such a claim must be supported by additional information, researches and calculations of the expected level of the Madagascar shrimp population.

The author's arguments leading to the conclusion that the Madagascan shrimp will quickly become an endangered species are rather logical and consistent, but they are not able to be evaluated as cogent ones. Additional information based on researches, investigations and calculations must be given to check the plausibility of author's conclusion.
