Question

Undeterred by obstacles,he persevered in his efforts

Answer 1

The complete question is:

Undeterred by obstacles, he persevered in his efforts.

Start with: Without…

Without being deterred by obstacles, he persevered in his efforts.

• In the given sentence, the meaning of the word 'deterred' is discouraged or demoralized.
• So, the antonym(opposite word) is undeterred. Therefore, on starting the sentence with without, we use the opposite word in meaning as 'without' itself is a negative word and we cannot use two negative words together.
• The given sentence is a complex one as it joins a dependent and an independent clause without using any conjunction.
