The device is ____ small parts but can perform big tasks.

• A. familiar with
• B. capable of
• C. puzzled/confused/perplexed by
• D. in awe of

Answer: (B)

The main idea is expressing ability with the right prepositional phrase. “Capable of” is used to say something can do or handle something, often followed by a gerund or noun. In this sentence, the device is described as having the ability to deal with small parts while also performing large tasks, so “capable of” fits naturally. The other options try to attribute feelings or familiarity to a device—being familiar with means knowing or being acquainted with something; puzzled by and in awe of express confusion or admiration—neither of which describes an object’s ability to perform tasks. Thus the best choice conveys the device’s capacity to handle small parts and still achieve big tasks.
