And b) would make the following sentence more concise and clear?

Original sentence: In order to ensure that the project was completed on time, the team worked long hours and put in a lot of effort.

a) To ensure the project's timely completion, the team worked long hours and put in great effort.
b) To complete the project on time, the team worked long hours and put in great effort.

Both changes would make the sentence more concise and clear, but option b is slightly more concise and straightforward. It eliminates the unnecessary "in order to" and condenses the phrase "ensure that the project was completed on time" to "complete the project on time." Option a is also a valid improvement, but it uses the possessive form "project's timely completion," which may not be necessary depending on the context.

In higher altitude the density of O2 decreased and that's why body needs to produce more RBC with more Hb so they can compensate the low availability of O2 and breathing rate increased because body needs fast circulation of blood to provide O2 instantly to all cells so they don't feel low partial pressure of O2
