Living hundreds or thousands of years is possible. At least for certain trees! species like Longeva pine and aristata pine, typical of California, in the United States, can survive up to nine thousand years. The pink cedar, the jacarandá-da-bay, the Jatobá and the Pink jequitibá are examples of centuries-old trees found in Brazil.
But why do these trees live so long? In common, they have one characteristic: they are slow-growing trees. They take a long time to grow because they produce a high density wood, that is, a harder wood, more compact, which takes longer to form than a less dense wood and therefore less compact.
Brazilian centenary trees, such as rose cedar, jacarandá-da-bay and araucaria have plenty of wood. compact and live for about 500 years or more […] But how do scientists manage to define the age of trees as these
To do so, they just need to remove a cylinder about one centimeter in diameter from the trunk, using a special tool, similar to a corkscrew, and count the number of rings she has. it presents. These rings are formed by the radial growth of the tree, that is, from the center outwards. Generally, one ring appears per year in species from temperate countries. So a tree like Longeva pine, at nine thousand years old, would have nine thousand rings! In the case of species with a tropical climate, such as those in Brazil, the rings are not always annual, making them more difficult to interpret.
By knowing how old a tree is, scientists can discover, for example, what changes the Earth's climate has undergone over the years. After all, in times when the climate is warmer and rainier, the rings formed on the trunks of trees are wider than those that appear in periods of lower temperatures and less rain. Not curious?

( ) the feeling of fear.
( ) the feeling of wonder.
Question 3 – In the passage “[…] are examples of centuries-old trees found in Brazil.”, which trees does the text refer to?
Question 4 – In the segment “They take a long time to grow why produce high-density wood […]”, the highlighted term could be replaced by:
( ) "but".
( ) "because".
( ) "that is why".
Question 5 - In “The Brazilian centenary trees, such as the rose cedar, the jacarandá-da-bay and the araucaria have wood quite compact […]”, the underlined word:
( ) defines.
( ) intensifies.
( ) complements.
Question 6 – In the excerpt below, there is a word that indicates mode. Underline it:
"But how do scientists manage to define the age of trees like these?"
Question 7 – According to the text “[…] a tree like Longeva pine, at nine thousand years old, would have nine thousand rings!”. Check the reason:
( ) "These rings are formed by the radial growth of the tree, that is, from the center outwards."
( ) "Generally, one ring appears per year in species from temperate countries."
