Bonus Question!

Which of the above sentences would still be grammatically correct if you omitted the relative pronoun?


1. who
2. where
3. whose
4. which
5. which
6. whose
7. which
8. who
9. where
10. which

Answer to the bonus question

You can omit the relative pronoun in 4. and 7.

Relative pronouns can be omitted IF they refer to the object of the verb and not the subject.

4.  I’m not a fan of the music they play on this radio station.
7.  Where are the biscuits I bought this morning? Don’t tell me you’ve eaten them already!

They (subject) play the music (object)
I (subject) bought the biscuits (object)

My advice: If you feel more comfortable NOT omitting the relative pronoun that is perfectly fine! Both ways are okay. What’s more, as you become more and more confident with your English skills you may start to know instinctively when you can leave out the relative pronoun.

Pangolins are shy and quirky-looking creatures. They are unique in that they are the only mammals with scales.

These scales are made of keratin, the same substance found in hair, fingernails, and a) __________. Thanks to their appearance, behaviour, and diet, pangolins are sometimes known as scaly anteaters. 

Yet, despite their appearance, pangolins are actually more closely related to carnivores such as dogs and b) __________. It’s strange when you consider that pangolins don’t have teeth!

There are eight different kinds of pangolin, including the black-bellied pangolin and the Sunda pangolin. Four species are c) __________ to Asia and four to Africa.

Depending on their species, they are found in a wide variety of habitats from tropical d) __________ to savannah or desert. Most live on the ground but some are tree-dwelling.

These solitary, and generally nocturnal creatures have a long slender snout and a e) __________ long tongue. Fully stretched, it’s about forty centimetres long! The tongue is narrow and sticky, perfect for slurping up insects from tunnels and hard-to-reach places. 

Their strong f) __________ allow them to rip into ant and termite mounds or to tear g) __________ off trees.

Since they don’t have teeth, pangolins h) __________ insects whole. They ingest stones and they also have spines inside their stomach which help to break down their food.

Pangolins play a vital ecological i) __________ in that they help to keep down ant and termite populations. This is why they are known as guardians of the forest. It is estimated that, thanks to their j) __________ appetite, pangolins can polish off seven million insects a year!

To protect them while they are foraging, pangolins have strong muscles which help to seal shut their nostrils and ears so that the ants and termites can’t bite them.

When threatened pangolins behave like armadillos and hedgehogs – they roll up into a tight ball. Their hard scales act like a suit of armour, protecting their head and soft belly. This is in fact how pangolins got their name –  ‘pengguling’ in Malay means ‘something that rolls up’. 

This defensive ball can k) __________ predators as formidable as lions, but unfortunately, it’s this very posture that makes them so easily caught by humans who can just pick them up.

Pangolins don’t have big broods. African pangolins usually give birth to just one pup, whilst Asian pangolins only have one to three l) __________. When they are born the pangopups have soft scales which soon harden. The mothers will curl around their young to protect them while they are sleeping or if they sense danger.

Not so fun facts

Tragically, these gentle and fascinating creatures face immense threats to their survival such as poaching and habitat loss. 

They are regarded as the most trafficked mammal in the world, due to a high demand for their meat and scales. 

In some areas of Asia, pangolin meat is regarded as a delicacy and pangolin scales are used in traditional medicine, despite the fact that, as with rhino horn, there is no scientific evidence of health benefits. 

All eight species are listed as threatened with extinction, two are critically endangered.

Pangolin rolled into a tight ball. Stony ground.
