In the concluding paragraph, the author notes that Takeshita faces difficult challenges — tax reform and trade tensions with the U.S. — and remarks that “there is nothing to show yet that he will be drawing on secret reserves of dynamism.”
This indicates a skeptical but fact-based view of his potential success, grounded in observation rather than hostility or admiration.
Option (a) cautious optimism — incorrect, as there is little suggestion of optimism in the author’s evaluation.
Option (b) enthusiastic adulation — clearly not the tone; the author is reserved and critical.
Option (d) undisguised derision — also incorrect; there is no mockery or contempt in the language used.
Thus, (c) is correct — the tone is skeptical but objective, avoiding emotional extremes.
