PTE Reading Fill in the Blanks answers:
A: Suggests – There are two options, “suggests” or “recommends”, both words mean put forward consideration, but suggest also means that put one to think that something is the case. The context here is that “the coastal hypothesis” put one to think that an economy based on marine mammal hunting….., thus suggests is more suitable choice
B: Because – There are two options – “Because” and “In spite” to choose from, it can be clearly seen that the “the barrier of ice to the east, the Pacific Ocean to the west, and populated areas to the north” is the reason why people move in a southerly direction, so “Because” is the correct connector to link cause and effect.
C: Impetus – Option C has to be a noun as it is after the adjective, eliminate all other parts of speech, “impetus” and “speed” are the only nouns available. The correct answer is impetus as it means “something that makes a process or activity happen or happen more quickly”, which indicates more and more people have been moving to the South.
