33. We’ve come (in / on / to) under budget. - The correct answer is "in". We use the preposition "in" after the verb "come" to indicate being within or inside a certain condition or limit. In this case, it means that we have come within the budget and have not exceeded it. 32. They fell behind schedule but have managed to catch (on / by / up) this week. - The correct answer is "up". We use the phrasal verb "catch up" to mean to reach or come up to the same level or standard as others. In this context, it means that they have managed to reach the same level or progress as planned after falling behind. 33. But this is likely to lead (from / to / by) dissatisfied employees. - The correct answer is "to". We use the preposition "to" after the verb "lead" to indicate the result or consequence of something. In this case, it means that the situation is likely to result in or cause dissatisfied employees. 34.

In this case, it means that the fall was caused by a number of factors, including the events in September. 37. I think you’ll find a (little / few / slightly) differences to the new prototype. - The correct answer is "few". We use the determiner "few" before plural countable nouns to indicate a small number.
