Here's a short story:

The word "animal" comes from the Latin animalis, meaning having breath, having soul or living being. In everyday non-scientific usage the word excludes humans – that is, "animal" is often used to refer only to non-human members of the kingdom Animalia; often, only closer relatives of humans such as mammals, or mammals and other vertebrates, are meant. The biological definition of the word refers to all members of the kingdom Animalia, encompassing creatures as diverse as sponges, jellyfish, insects, and humans. 

All animals have eukaryotic cells, surrounded by a characteristic extracellular matrix composed of collagen and elastic glycoproteins. This may be calcified to form structures like shells, bones, and spicules. During development, it forms a relatively flexible framework upon which cells can move about and be reorganized, making complex structures possible. In contrast, other multicellular organisms, like plants and fungi, have cells held in place by cell walls, and so develop by progressive growth. Also, unique to animal cells are the following intercellular junctions: tight junctions, gap junctions, and desmosomes. (End of story)

Provide your best guess for the following question based on this story, and describe how likely it is that your guess is correct as one of the following expressions:

Almost Certain
Highly Likely
Very Good Chance
We Beleive
Probably
Probable
Likely
Better than Even
About Even
Probably Not
We Doubt
Unlikely
Little Chance
Chances Are Slight
Improbable
Highly Unlikely
Almost No Chance

Give ONLY the guess and your confidence, no other words or explanation. For example:

Guess: <most likely guess, as short as possible; not a complete sentence, just the guess!>
Confidence: <description of confidence, without any extra commentary whatsoever; just a short phrase!>

Here are a few examples of questions and answers:

Question: Animal originates from what language?
Guess: Latin
Confidence: <appropriate level of confidence in this guess>

Question: Animal excludes what species?
Guess: humans
Confidence: <appropriate level of confidence in this guess>

Question: To which kingdom does it refer?
Guess: Animalia
Confidence: <appropriate level of confidence in this guess>

Question: Animals have which type of cells?
Guess: eukaryotic cells
Confidence: <appropriate level of confidence in this guess>

Question: What makes up their matrix?
Guess: collagen and elastic glycoproteins
Confidence: <appropriate level of confidence in this guess>

Now answer the following question in the same format.

Question: What structures form if these components calcify?

shells, bones, and spicules
