Have a go at practice verbal reasoning test questions for training contract applications on biology!

Biology is a subject area in the brand new innovative, independent, platform for practising online verbal reasoning assessments called ‘Legal Recruit‘.

Hope you enjoy these questions.

1          Every day, we are bombarded with scientific and medical claims that are not based on good evidence: in advertising material, product websites, advice columns, campaign statements, celebrity health fads and policy announcements. Even where there is some regulation, in advertising or trading standards, such claims keep reappearing.  “Sense About Science”, along with over 5,000 scientists, scientific bodies, research publishers and policy makers, don’t want people to continue getting away with making claims without supporting evidence. They want things to change, so that anyone making a claim expects to be challenged, and is made to stand by their words. The only way to do this is to get more people asking for evidence.

 

Q1 Campaign statements are never based on good evidence.

 

CANNOT SAY. ‘Campaign statements’ are given as examples of scientific and medical claims which are not based on good evidence.

 

Q2 “Sense About Science” wants people to continue getting away making claims without supporting evidence.

 

FALSE. The passage states the precise opposite.

 

2          We hear about bacteria for lots of different reasons, and it’s unusual for many of them to be ‘good’. Indeed, the last time most people probably remember seeing bacteria make headlines was the contamination of salad vegetables with a deadly Escherichia coli strain relatively recently. However, as any microbiologist will tell you, bacteria are an extremely diverse group of organisms, with equally diverse properties which make some of them indispensable for many aspects of our lives; including food production, digestion and water treatment. For example, Geobacter sulfurreducens is just one of many bacterial superheroes. In this case, its superpower is ‘bioremediation’; the use of its metabolism to remove pollutants from the environment.

 

Q3 There is a very narrow range of strains in the bacteria class.

 

FALSE. Bacteria are stated to be an extremely diverse group of organisms.

 

Q4 Bacteria are never used for water treatment.

 

FALSE. Bacteria are said to play an ‘indispensible’ role in many functions, including water treatment.

 

 

3          While some birds only migrate locally in response to extreme weather conditions, others undertake seasonal long-distance migration between land masses and sometimes hemispheres.  The most impressive avian migrator is, by far, the Arctic tern (Sterna paradisaea). Weighing an average of 100g, with a average wingspan of 75 – 85 cm, the birds sometimes nest just once every three years, as so much of their 30 year life span is spent in flight. The bird has the longest seasonal movement than any other animal, and the birds move so consistently with the seasons that they only ever see long days; they experience more sunlight per year than any other creature.

 

Q5 80 cm is a reasonable estimate wingspan of the African tern.

 

CANNOT SAY. The information given only refers to the Artic tern.

 

Q6 It is rare for the Artic Tern to be exposed to sunlight, compared to other creatures.

 

FALSE. The passage states that the Artic Tern ‘experience more sunlight per year than any other creature’.

 

4          There’s actually 47 known species of ‘leafcutter ants’, endemic to South and Central America, which live in colonies of up to ten million individuals organised into a complex social structure. The leaf cutting ants don’t actually eat the leaves they harvest – this is part of an elaborate process of cultivating a mutualistic fungus, which in turn provides the ants with the nutrients on which they feed. Efficiency of fungal cultivation is dependent on roles played by distinct ‘castes’ of ants, based mostly on size. Large workers forage for leaves and defend the colony, while smaller workers farm the fungus and tend to the nest. There’s even a designated waste removal team.

 

Q7 There are currently over 50 species of ‘leafcutter ants’.

 

CANNOT SAY. The passage states that there are 47 ‘known species’ of ‘leafcutter ants’, but it is not known how many unknown species of ‘leafcutter ants’ there currently are.

 

Q8 Only the caste of ants determines the efficiency of fungal cultivation done by ants.

 

FALSE. The passage states that distinct ‘castes’ of ants determine the efficiency of fungal cultivation done by ants.

 

 

5          Obesity is a growing problem worldwide, but proper protein consumption can help keep it at bay. Researchers have found that, when subjects were fed a 10% protein diet, they consumed 12% more energy over four days than they did on a 15% protein diet. Moreover, 70% of the increased energy intake on the lower protein diet was attributed to snacking. When the protein content was further increased to 25%, however, the researchers observed no change in behaviour relative to the 15% protein diet. It had previously been suggested that protein content plays an important role in determining overall energy intake, and thus affects obesity, but until this study, experimental verification had been lacking.

 

Q9 Obesity is only a problem in the U.S.

 

FALSE. Obesity is said to be a ‘growing problem worldwide’.

 

Q10 Protein content plays an important role in determining overall energy intake.

 

CANNOT SAY. No definite conclusion can be drawn from this study. Despite the findings of this study, the statement could still be true.

 

 

6          The anti-obesity properties of resveratrol have been demonstrated for the first time in a primate. Researchers recently studied the compound, generated naturally by plants to ward off pathogens, which has received much interest as a dietary supplement for its supposed life-extending effects. A team of researchers from Paris have decided to investigate the effect of dietary supplementation with resveratrol on the weight, metabolism and energy intake of six mouse lemurs. The physiological benefits of resveratrol are currently under intensive investigation, with recent work suggesting that it could be a good candidate for the development of obesity therapies. The team found that lemurs eating a diet supplemented with the compound decreased their energy intake by 13% and increased their resting metabolic rate by 29%.

 

Q11 Based on research in the rat, resveratrol could be a good candidate for the development of anti-obesity therapies.

 

CANNOT SAY. The research described used a sample of lemurs (primates).

 

Q12 In this study, lemurs eating a diet supplemented with the compound increased their energy intake by an average of 13%.

 

TRUE. This is a finding from this study.
