IELTS Cambridge 14 Test 4: AC Reading Module
Reading Passage 1:

The headline of the passage: The secret of staying young

Questions 1-8: (Completing notes with ONE WORD ONLY)

[In this type of question, candidates are asked to write only one word/ no more than two words to complete a note on the given topic. For this type of question, first, skim the passage to find the keywords in the paragraph concerned with the answer, and then scan to find the exact word.]

Title: Ysabel Giraldo’s research

Question 1: Focused on a total of _________ different age groups of ants, analysing

Keywords for the question: focused, total, age groups, ants    

The answer is in paragraph no. 3 in the very beginning in lines 1-2, “In the lab, P. dentata worker ants typically live for around 140 days. Giraldo focused on ants at four age ranges: 20 to 22 days, 45 to 47 days, 95 to 97 days and 120 to 122 days.”

So, the answer is: four / 4

Behaviour:

Question 2:

  • how well ants looked after their ___________

Keywords for the question: how well, ants, looked, after    

The answer is in the first line of paragraph no. 4, “Giraldo watched how well the ants took care of the young of the colony,  .. . ..”

Here, took care = looked after

So, the answer is: young

Question 3:

  • their ability to locate ___________ using a scent trail

Keywords for the question: ability, locate, using, scent trail,

The answer is found in lines 2-3 of paragraph no. 4, “.. ..She compared how well 20-day-old and 95-day-old ants followed the telltale scent that the insects usually leave to mark a trail to food.”

Here, mark = locate, how well = their ability,

So, the answer is: food          

Question 4:

  • the effect that _______ had on them

Keywords for the question: effect, had on them,  

The answer can be found in lines 3-4 of paragraph no. 4, “She tested how ants responded to light . .. .”

Here, how ants responded = the effect ..…. had on them

So, the answer is: light           

Question 5:

  • how _________ they attacked prey

Keywords for the question: how, attacked, prey,

The answer is in the last lines of paragraph no. 4, “.. ..And when it came to reacting to prey, the older ants attacked the poor fruit fly just as aggressively as the young ones did, .. ….”

Here, attacked the poor fruit fly = attacked prey,

So, the answer is: aggressively          

Brains:

Question 6:

  • comparison between age and the ___________ of dying cells in the brains of ants

Keywords for the question: comparison, age and, dying cells, brains of ants,   

Paragraph no. 5 talks about the research on ants’ brains. Here, in lines 1-3, the author says, “Then Giraldo compared the brains of 20-day-old and 95-day-old ants, identifying any cells that were close to death. She saw no major differences with age, nor was there any difference in the location of the dying cells,  .. ..”

So, the comparison was between ants’ age and location.

So, the answer is: location     

Question 7:

  • condition of synaptic complexes (areas in which _______ meet) in the brain’s ‘mushroom bodies’

Keywords for the question: synaptic complexes, mushroom bodies,  

The answer is found in lines 4-6 of paragraph no. 5. The author says here, “Ants and other insects have structures in their brains called mushroom bodies, which are important for processing information, learning and memory. She also wanted to see if ageing affects the density of synaptic complexes within these structures – regions where neurons come together.”

Here, synaptic complexes mean the region of ant’s brain where neurons come together or meet.

So, the answer is: neurons    

Question 8:

  • level of two ________ in the brain associated with ageing

Keywords for the question: level of two, associated with ageing,  

The answer is in lines 7-9 where the author talks about two chemicals. “.. .What was more, the old ants didn’t experience any drop in the levels of either serotonin or dopamine – brain chemicals whose decline often coincides with ageing.”

Here, serotonin and dopamine are the two chemicals, coincides with ageing = associated with ageing,

So, the answer is: chemicals  

Questions 9-13: In this type of question, candidates are asked to find out whether:

The statement in the question agrees with the information in the passage – TRUE

The statement in the question contradicts with the information in the passage – FALSE

If there is no information on this  – NOT GIVEN

[For this type of question, you can divide each statement into three independent pieces and make your way through with the answer.]

Question 9: Pheidole dentata ants are the only known animals which remain active for almost their whole lives.

Keywords for the question: Pheidole dentata, only known animals, remain active, almost, whole lives,

The answer lies in the first lines of paragraph no. 2, where the author mentions ‘naked mole rats’. “Naked mole rats can live for almost 30 years and stay fit for nearly their entire lives.”

So, Pheidole dentata ants are not the only known animals which remain active for almost their whole lives.

So, the answer is: FALSE

Question 10: Ysabel Giraldo was the first person to study Pheidole dentata ants using precise data about the insects’ ages.

Keywords for the question: first person, study, Pheidole dentata, using, precise data, ages,    

The answer is in paragraph no. 3 in lines 2-4, “. … . ..Unlike all previous studies, which only estimated how old the ants were, her work tracked the ants from the time the pupae became adults, so she knew their exact ages.”

Unlike all previous studies means the research works done by previous scientists did not use data about insects’ age, and naturally Ysabel Giraldo was the first to do so.

So, the answer is: TRUE

Question 11: The ants in Giraldo’s experiments behaved as she had predicted that they would.

Keywords for the question: ants in Giraldo’s experiments, behaved, predicted, they would,   

In paragraph no. 5, the answer lies in lines 6-7, “She also wanted to see if ageing affects the density of synaptic complexes within these structures – regions where neurons come together. Again, the answer was no.” Previously, in the same paragraph, lines 1-3 suggest that Giraldo wanted to identify any cells that were close to death but she saw no major differences with age.

This means the experiments did not show results as she expected.

So, the answer is: FALSE

Question 12: The recent studies of bees used different methods of measuring age-related decline.

Keywords for the question: recent studies, bees, different methods, measuring age-related decline,    

In paragraph no. 6 we can see the reference of ‘bees’. But we do not find clear information on whether the recent studies of bees used several methods of measuring age-related decline.

So, the answer is: NOT GIVEN

Question 13: Pheidole dentata ants kept in laboratory conditions tend to live longer lives.

Keywords for the question: Pheidole dentata ants, kept in laboratory, live longer,

The answer is in paragraph no. 7. In the first lines the writer states, “Out in the wild, the ants probably don’t live for a full 140 days thanks to predator, disease and just being in an environment that’s much harsher than the comforts of the lab.”

These lines suggest that ants kept in laboratory conditions live longer than ants living in the wild.

So, the answer is: TRUE
