In this argument, the author reaches the conclusion that Largo Piano Company should introduce a line of digital pianos in a variety outsell of price rangers to increase Largo’s sales and revenues. To support the argument, the author points out the fact that the company’s revenues have declined during the past few years. Furthermore, he also cites the example that after introducing a line of inexpensive digital pianos, the Allegro Musical Instrument Company sew its increase revenue(revenues increased). Closely examining the author’s logical and reasoning, we can find that neither of these reasons provides sufficient support for the conclusion and this argument suffers two serious logical flaws. In the first place, the author commits the “after this and therefore because of this” fallacy where the author assumes that the Allegro Musical Instrument Company’s revenue increase occurred after the company introduce(introduced) a line of digital pianos, the introducing(introduction) of a line of digital pianos was responsible for the increase of the Allegro company’s revenue. However, the relationship between two issue mentioned above cannot establish the causality relationship. In fact, the author may ignore the possibility of the other alternative factors such as large advertisement of the Allegro Company, which may contribute to the increase in the revenue of the Allegro Company. It may be only a coincidence that the Allegro Musical Instrument Company saw its increase revenue after introducing a line of inexpensive digital pianos. Unless the author rules out the possibility of the other alternative factors, the argument is in question and cannot be accepted. In the second place, the author fails to assume that the Largo Company can achieve the same results as the Allegro Company, if the Largo Company also introduces a line of digital pianos. Nevertheless the argument uses a faulty(false) analogy between the Allegro Company and the Largo Company; analogies drawn between the two fields are highly suspect because there are many serious differences. The Largo Piano Company, for example, has long been known for producing carefully handcrafted, expensive pianos used by leading concert pianists. But the Allegro Musical Instrument Company met the demand of common customers instead of the performer’s(performers). So dissimilar that the Largo company is unlikely to experience the same consequence if the company adopts the strategy of the Allegro company. In sum, the author commits the above discussed logical mistakes and fails to consider the whole situation comprehensively, his ideas should not be adopted. To make the argument logically acceptable, the author should provide additional information listed in the previous analysis. Buttressed with more evidence, the argument can be more convincing.(这一句话和之前一句是一个意思吧)
