Rule reminder
At B2 level, choosing connectives requires understanding the whole paragraph, not just the adjacent sentences. The correct connective must fit: (1) the logical relationship between clauses, (2) the register of the text, (3) the overall argumentative direction of the paragraph. Common traps: a connective that is logically possible but changes the tone; a connector that fits locally but breaks the paragraph's flow.
PARAGRAFO: 'I dati mostrano un aumento significativo della domanda. ___, l'offerta non è riuscita ad adeguarsi con la stessa rapidità. ___, i prezzi hanno subito un'impennata.'
