Well, that is one hypothesis. But it is unlikely to stand up to scientific sorutiny.
And a surprising amount of such scrutiny is being devoted to the question of why
trees turn such glorious colours
In deciduous woodland, the first signs of approaching autumn are written
across the forest in shades of yellow and orange. Lower temperatures and
shorter days trigger the breakdown of chlorophyll - the green molecule that
captures energy from light in the process of photosynthesis.
As the chlorophyll is removed, it reveals other pigments that have been
swamped by its bold colour. These are called caratenoids. They aid the process
of absorption and in chlorophyll's absence, give rise to pale and brilliant yellows
ambers, golds and oranges. Different species of tree retain different amounts of
caratenoids, which leads to much of the polychromatic beauty of a forest in
autumn

Answer 1

Resposta:

1. Resposta e -

A pergunta que não pode ser respondida a partir da informação dada pelo texto

é:

“What elements compose the molecule of chlorophyll?”

“Que elementos compõem a molécula de clorofila?

2. Resposta d -

As = when = quando

“As autumn arrives...”= Quando o inverno chega...

a)Wherever = onde quer que

b) for = pois, para

c) then = então

e)It = pronome pessoal neutro da terceira pessoa do singular.

3. Resposta e –

A expressão “sport it” pode ser substituída sem alteração de sentido por “wear it”

b) to play = brincar, jogar, tocar

c) to leave = sair, deixar, partir

d) to turn = virar

4. Resposta d –

*Bem, essa é um hipótese. Mas é improvável que resista a uma investigação

científica.  

5. Resposta c –

*to trigger = to cause = causar, provocar

*to avoid = evitar

*to lessen = diminuir

*to prevent = impedir

*to destroy = destruir
