Choose the correct word/phrase to go in the gap.
It’s better not to use ‘shows’ as then you are copying from the question. Graphs are not an explanation, so it is not ‘explains’. So ‘illustrates’ is best.
Looking at all the expenditure items, the changes are quite erratic over the whole time frame, so ‘fluctuation’ is the best description.
More was spent on food than clothing and gas, so ‘the most’ is correct. We can’t say ‘high money’.
They followed an opposite pattern, as food rose then fell.
The first and last options have no main verb, so it has to be the second choice ('Clothing expenses' is the subject for this verb).
It is past simple for completed actions/events in the past, not past continuous (choice 1) or present simple (choice 2).
‘However’ would need to follow a full-stop, as would ‘in contrast’. ‘Whereas’ is the only one that fits.
The prepositional phrase fits. ‘Finalise’ is the wrong word form. It can’t be a main verb (finished) as there is no subject.
Around $310 was spent on food, with around $640 spent on clothing. So ‘more than double’ fits here.
The last two choices do not fit grammatically. It should be the noun form.
