hello there the answer is true
Well,
The answer would be the number 3
why? because in the beginning when Ferdinand de Lesseps, a french engineer who built the swiss canal decided to create one in the isthmus of Panama due to its ideal location and width to save a lot of time and money on travels, they brought over from France workers and machines, used to create the swiss canal previously, but due to the clay soil and the tropical conditions they quickly broke, forcing workers to do most of the work manually.
Also, due to the heat and the still water, mosquitoes carrying different diseases like malaria and dengue, swarmed the area biting and infecting the workers, ultimately killing most.
Making them give up the whole project.
since the 1800s theres been a lot of rebelius uprisings on the balkans expecialy in the begining of the 1900s(Ilinden Uprising) then the Ottoman Empire was at war (First Bakan War 1911-12) with Montenegro(started the war), Serbia, Macedonia, Bugaria and Greece in 1913(2nd Balkan war) Greece, Serbia, and Bugaria divided Macedonia Greece took Aegon Macedonia Serbia took Vardar Macedonia Bugaria(stared the war) took Pirin Macedonia(smalest part) ---- Ottoman Empire, after 1700s had to maintain status quo for falling technologicaly and economicaly apart from European counterparts. Diplomaticaly it could have lost its existence long time ago if England and France did not prevent Russia from further advancing. However at the last times of the empire English left supporting and Italy invaded Tripoli, at that time with Russian support Balkan Wars began which was probably the greatest defeat of Ottoman Empire, by the countries it ruled for 4 centuries directly or as vassals. As nobody wanted to ally with Ottoman Empire, Germany was only country that was interested in allying. Great German aid was made, in both army and industry. Construction of Istanbul-Baghdad railroad was also maintained by German industry. Under this pro-German aids Ottoman Empire sought to gain its old power, at least on Balkans, which was so close to its capital and were highly populated by Turkish population. Note: By the Ottoman official records 2,5 million immigrants came from newly founded countries which is a real high number as Turkish population of Ottoman Empire was about 10 millions before WW1.
