Pay close attention to the spelling of comparative and superlative forms of short adjectives, especially those that double their final consonant like 'big' to 'bigger' and 'biggest'.
Do not confuse the capabilities of penguins: the exam may test the fact that they CANNOT fly, but they CAN swim exceptionally well.
Remember the distinction between 'can' (ability) and 'must' (necessity/obligation) as they are used to describe animal survival behaviors in the exam.
Memorize the three idioms: 'the lion's share' (the largest part), 'curiosity killed the cat' (being too curious is dangerous), and 'crying wolf' (raising false alarms). These are highly likely to appear in dialogue completion questions.
Associate each animal with its correct habitat from the text: elephants/tigers with forests, zebras/giraffes with the savanna, and penguins with Antarctica.
