A. Compute the DeRham cohomology (or if you prefer, the singular homology) of \((S^2\times S^2)\#\mathbb {C}P^2\), where, \(M\#N\) denotes the connected sum of the manifolds \(M\) and \(N\).
B. Let \(p\) be a positive integer. Compute the singular homology with coefficients in \(\mathbb {Z}_p\) of real projective 3-space (\(\mathbb {Z}_p\) being the cyclic group of order \(p\)). That is, find \(H_k(\mathbb {R}P^3,\mathbb {Z}_p)\) for \(k\ge 0\).
