An 'Assumption' is something supposed or taken for granted. In these questions, a statement is given followed by two assumptions. You need to decide which assumption is 'implicit' (hidden reasoning) in the statement.
Assumptions containing words like 'Only', 'Best', 'Strongest', 'All', 'Every' are often invalid because they are too restrictive. Words like 'Some', 'May', 'Possible' often make an assumption valid.
