6. Answer: location
Explain
– Key words: comparison, age, dying, cells, brains
– In paragraph 5, we know that Giraldo didn‟t find any major difference in age and the location of dying brain cells between 20-day-old and 95-day-old ants. This suggests that she compared between the age and location of dying cells.
7. Answer: neurons
Explain
– Key words: synaptic, complexes, brain‟s, mushroom bodies
– In paragraph 5, it is stated that synaptic complexes are “regions where
neurons come together”
8. Answer: chemicals
Explain
– Key words: two, brain, associated, ageing
– Still in paragraph 5, we are told that Giraldo studied the level of serotonin and dopamine, which are two “brain chemicals whose decline often coincides with aging”. This implies that they are associated with aging. Thus, the answer is “chemicals”.
9. Answer: FALSE
Explain
– Key words: Pheidole dentata remain, active, whole, life
– In paragraph 2, the author mentions naked mole rats as an age-defying
animal: they stay fit for nearly their entire lives and they can reproduce even when old. It can be said that they remain active for almost their whole life. Thus, Pheidole dentata ants are not the only animal with this feature.
10. Answer: TRUE
Explain
– Key words: Ysabel Giraldo, first, Pheidole dentata precise, data, age
– It is stated in paragraph 3: “Unlike all previous studies, which only estimated how old the ants were…she knew their exact ages”. This means that she was the first person to use the ants‟ exact ages in her studies.
11. Answer: FALSE
Explain
– Key words: ants, Giraldo‟s experiments, behaved, predicted
– It is stated in paragraph 4 that “Giraldo expected the older ants to perform
poorly…but the elderly ants were all good caretakers and trail-followers”. This implies that the elderly ants behaved differently from what she expected (predicted). She thought that they would perform badly, but they performed well.
