There are two verb tense errors in this paragraph. correct them: indeed,,,1900.thesebicycles-on-’sae ronauts,,000francs,10metres.

Indeed, whilst the Chinese allegedly strapped prisoners onto kites in the sixth century, and Elmer of Malmesbury was recorded as having glided for more than an eighth of a mile before crashing and breaking both his legs, it was not until the start of the 1900s that scientific attempts WERE made to get a man off the ground under his own steam. These bicycles-on-wheels might seem comical to today’s aeronauts, but in 1912 they WERE good enough to help Gabriel Poulain scoop a prize of 10,000 francs, having allegedly flown his contraption more than a meter off the ground for distance of 10 meters.

Explanation:

In these examples, we should use Past Simple tense instead of Present Simple tense, as the paragraph describes an event from the past. There also are some adverbs of time (e.g. until the start of the 1900s and in 1912) which suggest to us that we should use Past Simple tense and not Present Simple tense.

the correct answer is option d. none of these. it is noted that options a, b, and c share the same content.

despite the valid answer provided at the last sentence of each of the options, a question/answer format shouldn't include humourous themed responses such as "you bet your thermal pj's we do." - unless of course, the answer is carried out in an informal environment. this could be replaced with a simple "yes" or "it is necessary".

the question should be re-phrased to a more appropiate syntaxis. instead of "do we need the greenhouse effect? ", it should be written as "is the greenhouse effect necessary? " in order to give it a general scope, instead of limiting the answer to the needs of "we" the humans.
